stewartElizabeth Quay Pedestrian and Cyclist Bridge: Artfully Structuring Complex Curves with Parametric Design

Abstract. A striking engineering feat, the Elizabeth Quay pedestrian and cyclist bridge is a 110m, cable-stayed bridge, which spans the Quay’s inlet and offers impressive 360 degree views across the Swan River and the Perth CBD. An artfully meandering structure, the ‘S’ shaped bridge allows for continuous movement around the Quay and was designed to delight those who use its curvaceous form. Shaped by diverse and innovative design influences, the architectural, artistic, structural and functional final form of the bridge is considered to be more a unique, trafficable sculpture, than a typical pedestrian bridge. Arup’s innovative use of parametric design tools to structure complex curves, addressed three design challenges set by the client and produced a structure that is simple, iconic and elegant.

stewartMaterial Selection and Compliance with Structural Eurocodes

Abstract. The Structural Eurocodes are already fully implemented in Singapore with effect from April 2015. While it is useful to implement a set of technically advanced structural design codes from Western Europe, it is important to take cognizance of the fact that Singapore is not part of the European Union. We are a small island city state with an open market economy and most of our structural materials for construction are coming out from the Asia-Pacific region, and they are manufactured to a variety of international product standards. It is untenable to insist that only construction materials manufactured to European standards can be used in Singapore because of our geo-physical and geo-economical position within the Asia-Pacific region. This presentation will provide the background and trace our journey to develop a design guide on selection of alternative structural materials manufactured to various international product standards for design to the Structural Eurocodes. The key issues and how to ensure quality in the material selection process will be presented.

han2Life-cycle based study on concrete-filled steel tubular (CFST) structures

Abstract. This presentation illustrates the characteristic behaviour and mechanism of concrete-filled steel tubes (CFST) in terms of the composite action between the steel tube and core concrete, typical failure mode, bearing capacity and ductility, effects of the concrete shrinkage and creep, bond between the steel tube and core concrete, effects of core concrete imperfection, as well as "two-stage design" philosophy. A review is conducted on the research of the CFST members in recent years. Recent major findings to demonstrate the static behavior of the CFST members under short-term/long-term sustained loading and corrosion, the structural responses of the composite members subjected to cyclic loading and impact, as well as the fire performance of the CFST columns are evaluated. A number of typical projects utilizing CFST members are reviewed and presented. Finally, the framework of life-cycle based theory of CFST structures will be introduced.

stewartPerformance of Sandwich Panel with Square Dome Shape Folded Kirigami Core under Blast Loading

Abstract. Structural response of sandwich panel with new Square Dome-shape Kirigami (abbr. SDK) core under blast loading is investigated in this study. The proposed new SDK core is folded using a single piece of patterned aluminium sheet. The SDK structure is tested under quasi-static loading condition and a numerical model is developed and calibrated based on experimental data. The calibrated model is then applied to simulate the structural response of the sandwich panel with the proposed SDK core under blast loading. Different boundary conditions are implemented to simulate structural response of the proposed structure for various potential applications, including sacrificial cladding protective structure where only the back layer of panel is fully fixed and stand-alone sandwich panel where boundary of the panel is fully clamped. Its structural response is compared with those of square honeycomb and existing cube strip kirigami structure with the same density. The damage modes and the structural responses including reaction forces at proximal and distal face sheet, back face deflection and energy absorption, are examined and compared to evaluate the performance of these sandwich panels. As compared with square honeycomb and cube strip kirigami foldcore, the proposed sandwich panel with SDK core shows superior performance by yielding a significantly reduced reaction force on distal face and high energy absorption for sacrificial cladding and reduced back face deflection for stand-alone panel.

stewartNew Developments in International Steel and Concrete Composite Design Standards

Abstract. Major developments are underway in composite standards worldwide. In Australasia, the first joint Australian/New Zealand steel and composite bridge design standard AS/NZS 5100.6 has been published, and it is expected that the first Australasian design standard on multi-storey composite construction AS/NZS 2327 will soon be published. In North America, the 2016 edition of the Specification for Structural Steel Buildings AISC 360-16 was published. Whilst in Europe, work on the second generation of Eurocode 4 is underway, which is expected to be published in 2020. Drawing on personal experience, the present author will provide a general overview of the work leading to the development of AS/NZS 5100.6 together with the ongoing work on Eurocode 4. As Chair of the Committee responsible for AS/NZS 5100.6, the author will present the work that has led to structural steel products manufactured to overseas standards to be permitted in design; moreover, the challenges faced in the development of composite design provisions from the introduction of concrete compressive strengths up to 100 MPa together with quenched and tempered steels with a yield strength up to 690 MPa will be presented. In addition, the ongoing work on developing new shear connector design provisions for Eurocode 4 will also be presented. From these developments, future research needs will be identified for the next generation of Australasian and European design standards.

stewartInnovative Flooring System for Steel-Concrete Composite Construction

Abstract. In recent years, there is an increased interest in structural flooring solutions that optimizing the structural floor depth which enable a significant reduction of the storey height. Composite slim floor structures which incorporate the steel beam in the floor depth leads to the possibility of reducing the storey height, which in turn, increasing the number of floors within the maximum allowable height of the building. A series of shear beam tests incorporated dowel reinforcement as shear connectors had been tested to evaluate the shear connector resistance and composite action of these beams. The objective of these tests is focused on the shear connector resistance of this form of composite beams, as well as the effects of clamping action due to eccentric loading. This paper presents the test arrangement and results obtained from the shear beam tests. Findings from this research will provide fundamental understanding to the behaviour of this important form of composite structures.

stewartResearch on Progressive Collapse Resistance of Steel Frames under Localized Fire

Abstract. The numerical and experimental studies on progressive collapse resistance of planar steel frames under localized fire are presented. A numerical model of a planer steel frame was built, and validated against experimental data and analysis results of other researchers. Then extensive parametric studies were conducted to study the possible progressive collapse mechanisms of planar steel frames when one column failed under elevated temperature. The investigated parameters included beam cross-sectional size, load ratio and location of the heated column. Besides, experimental studies were conducted to study the performance of planar moment steel frames with one column heated. The novelty of these tests is that the influences of key stages in the response of the heated column under gravity loading, including post-buckling and cooling phase after fire, on the progressive collapse resistance of steel frames were studied. Through the parametric studies, three progressive collapse mechanisms were found, namely, cantilever beam mechanism, pull-in force induced mechanism and column buckling failure mechanism, of which the last one is a new discovery. To evaluate progressive collapse of planar steel frames under fire, the cantilever beam mechanism and the pull-in force induced mechanism should be checked when an outer column is heated, and the pull-in force induced mechanism and the column buckling failure mechanism need to be checked when an inner column is heated. The test results show that steel columns with strong constraints from steel beams in a frame may fail in a quasi-static manner under fire, while those with weak constraints or large load ratios may fail with dynamic effects. Besides, the final equilibrium vertical displacement at the top of the column after dynamic buckling can be even larger than the final displacement associated with gradual column removal.

profliewDesign and Construction of Steel Structures of Wide Span Enclosure

Abstract. This paper presents the design and construction several long span steel structures built in Singapore. These unusual steel structures are perceived to have significant impact in transforming Singapore to become a global city.  Its complexity in terms of size, design, and craftsmanship was without equal in the modern history of space frame structure. The construction of these complex structures in a densely build-up urban environment required close collaboration between the designer and the builder using advanced analysis software and BIM for pre-construction visualization, fabrication and project execution. These structures were difficult to fabricate and constructed because of their unusual shapes and large span enclosure. Special efforts were needed to identify problems earlier and to design the joints for ease of transportation and safe construction. These projects also included sustainable and green design features in the development with an aim to lower carbon footprints, reduce their impact on biodiversity, operation energy, water usage, and thus minimize its impact to the built environment.   Steel structure is still the preferred choice for lightweight, long span and unusual shape construction.

stewartStrengthening Thin-Walled Cold Formed Steel Rack Structures

Abstract. Cold formed steel storage rack structures are widely used in different industries to store the products in safe and secure warehouses before distribution to the market. Racking systems lose their stability under lateral loads such as seismic actions due to the slenderness of elements and low ductility. This justifies a need for more investigation on methods to improve their behaviour and increase their capacity to let them survive medium or severe loads. In this paper an efficient way of increasing the torsional and distortional strength of the upright profiles will be introduced by using bolts and spacers reinforcement which is added externally to them. Extra bolts and spacers, which are spaced in certain pitches along the height, can restraint upright flanges and consequently increase the capacity of them. In order to check whether the uprights reinforced with bolts and spacers along the height can increase their load bearing capacity, experimental tests with upright frames both reinforced and unreinforced were performed and analyses were performed in ABAQUS software for both reinforced and standard upright frames. It is also attempted to point out the issues regarding the current seismic design assumptions of the cross aisle braced frame. In this part, energy method is used to evaluate the stability of a braced upright frame in cross aisle direction considering the seismic drift as well as the drifts due to base plate uplift. A displacement based method is then needed to be proposed to have a safer and more reliable design considering the destabilizing effect of lateral drift, so in this study a simple step by step displacement based method design of rack structures for cross aisle direction is proposed in which the overall stability criteria are taken into account.

stewartAssumptions that Lead to Failure

Abstract. Engineers involved in structural failures, failure investigations and the like, are often held to some form of legal suppression to not disseminate the findings to any third party. As a result, much learning is not disseminated and others make the same mistakes. Roles such as Professional Misconduct Investigator, Expert Witness (into structural failure or similar) and Inspectors or Investigators for Government regulators, are particularly fruitful in this respect. It is, nonetheless, important that findings relating to inadequate practices be disseminated in the interest of safety. This presentation highlights some common errors made, through examples specific to structural steelwork, from the presenter having operated in the above roles. The examples cover failures (collapses, near collapses or even non-performance), associated with buildings like stadia roofs, overhead travelling crane girders, boiler support structures and shopping centres. One common thread that runs through these failures is that assumptions were made, which were not validated as effective and verified during construction or in the field. Too often engineers assume that others will know their design intent, and that connections and members will have reserve capacity for the secondary effects not considered or considered inconsequential. From the examples, these assumptions often lead to failure. A related concern is the fact that mentoring of graduate engineers in real-life working environments has declined. Engineering firms now, more than ever, hire experienced contractors and are not retaining experienced staff to coach and mentor young engineers. This, together with the practice of using analysis programs, spreadsheets developed by others and ?cake mix design? without thorough validation of assumptions made, is a recipe for disaster.

stewartParametric Studies on 3-D Composite Floors subjected to Column-Removal Scenario

Abstract. This paper carries out parametric studies on three-dimensional steel-frame-composite-slab systems (3-D composite floors) subjected to column loss using macro-based finite element (FE) models, with beam elements simulating beams and columns, shell elements for composite slabs and connector (similar to spring) elements for joint components. The modelling method is verified by four actual experimental tests with three variables, Viz. slab aspect ratio, boundary condition and composite action between slabs and beams. To cover the deficiency of data acquisition in the actual tests, the FE models can be deeply exploited to investigate the effect of these variables on load redistribution and load contributions from individual structural members, such as double-span girder, double-span beam and composite slabs. In addition, the parametric studies are extended to influential factors, slab and steel decking thicknesses. Moreover, a steel skeleton frame is analysed and compared with a 3-D composite floor, to show how composite slabs and steel frames affect with each other and how much resistance can be increased due to the presence of composite slabs.

stewartSimplified Nonlinear Analysis of Steel-Concrete Composite Frames

Abstract. Second-order inelastic analysis considering material and geometric nonlinearities, initial imperfections, and residual stresses can be used to directly determine the system strength without using effective length factors and interaction equations. For this reason, this type of nonlinear analysis is often referred to as ?advanced analysis?. Many studies have been conducted on advanced analysis of steel framed structures, which promoted the adoption of this method in some design codes. But similar study on steel-concrete composite frames is still very scarce. Due to the high computational cost, detailed finite element (FE) models are impractical to use for nonlinear analysis of such composite frames. Therefore, efficient and accurate simplified models are highly desirable. In the present study, efficient simplified numerical models for composite frames consisting of concrete-filled steel columns, composite beams and composite slabs are developed using fibre beam elements, shell elements and connector elements available in ABAQUS. Proper material models are developed for the steel and concrete materials in composite columns, which are simulated by fibre beam elements. In the material models, the interaction between the steel tube and concrete, possible local buckling of the steel tube, and strain-hardening of the steel material have been implicitly considered. A shear load-slip model for shear studs is implemented in connector elements to simulate the possible slip between the composite slab and the steel beam. The behaviour of the composite connections is represented by simplified moment-rotation relations implemented in connector elements. This will allow the influence of connection rotation to be precisely considered in frame analysis. The developed simplified models are verified by extensive experimental results of composite columns, beams, connections and frames. The predictions agree very well with those test results, proving the high potential of the proposed models for conducting advanced analysis.

stewartHigh Strength Steel, Space and Composite Structures

Abstract. Central to innovation in modern infrastructure is the challenge associated with ever increasing spans of bridges and heights of building structures. Innovations in structural systems and their load paths can be used to tackle these challenges, however one of the critical elements is the development of higher strength members and systems which ultimately can reduce the construction economy. This paper will trace the developments of both steel and composite structures over the last century and the material developments that have been made in steel and concrete strengths over that time. These developments have influenced the development of steel-concrete composite systems and further contributed to innovative bridge and building solutions over that period. The paper will highlight issues associated with serviceability, strength, stability and ductility of high strength steel and composite structures. The applications and research in these areas will be addressed and the developments in the area of codification in international standards will also be presented. The paper will conclude by anticipating what the future challenges for future infrastructure will be and how both high strength steel and composite structures will be aligned to this future.

yamaInfluence of Collision on Mechanical Property of Steel Girder

Abstract. It happens sometimes that a bridge over a highway is damaged due to collision by a truck running underneath. Typical collision damages observed in a steel girder bride are as follows: a lower flange is deformed in the vertical direction and/or on the horizontal direction; a lower part of the web is bent together with the deformation of the lower flange; a transverse stiffener is buckled; and a transverse stiffener is partly removed from the web. The influence of the dame on the safety of the bridge has to be judged right away. Yet it is not always an easy task, since the load-carrying capacity of a deformed girder has not been studied much. The authors have been involved in the evaluation of two steel girder bridges damaged by collision. Based on the data acquired at those times, the load-carrying capacities of the deformed girders haven been studied numerically in the present study. To be specific, a deformed steel panel was loaded in various ways and the peak load was obtained. The results indicate that the collision damage surely influences the load-carrying capacity, but the influence is not so significant even when the deformation is much larger than the fabrication error allowed in the bridge design codes.

byoungCold-Formed Stainless Steel Double Shear Bolted Connections by Transient State Test Method

Abstract. A total of 37 cold-formed stainless steel double shear two-parallel and four-bolted connection specimens were tested using transient state test method. The specimens of bolted connections were fabricated by three different grades of stainless steel. The three different grades of stainless steel are austenitic stainless steel EN 1.4301 (AISI 304) and EN 1.4571 (AISI 316Ti having small amount of titanium) as well as lean duplex stainless steel EN 1.4162 (AISI S32101). The connection tests were conducted at three different load levels of 0.25, 0.50 and 0.75 of the failure load at ambient temperature. The tendency of the test strength reduction of the stainless steel double shear bolted connections conducted using the transient state test method is similar to those results obtained by the steady state test method. However, the critical temperatures obtained from the transient state test results are generally slightly higher compared with those deduced from the steady state test results at the three different load levels. The austenitic stainless steel grade EN 1.4571 (AISI 316Ti) generally performed better than the other two stainless steel grades in transient state tests as higher values of critical temperatures were obtained. Two failure modes, namely the bearing and net section tension failures, were observed in the transient state tests.
