Historic Steel Beam Reuse: A Case Study of a 100-year-old Warehouse
The production of steel accounts for approximately 9% of global C0₂ emissions today. The reuse of existing steel sections could drastically decrease this percentage. However, a lack of information about the material properties of existing steel sections can prove a barrier to steel reuse, …

Evaluation of Existing and New Test Configuration for Headed Shear Studs
Composite beams are frequently used in building, combining a steel beam with either a concrete-filled steel deck or solid concrete slab. To ensure proper composite action, shear connectors, typically in the form of headed shear studs, are utilized. Traditionally, the strength assessment of these …

Fatigue and static behaviour of post-tensioned steel-concrete composite beams
Strengthening steel and concrete composite (SCC) bridge superstructures using post-tensioned steel tendons offers many advantages. Since bridge structures are usually exposed to fatigue cycles, understanding the fatigue behavior of strengthened composite beams is vital. Also, bridges in practice …

Behaviour of long span composite beams with precast hollow-core slabs
… precast hollow-core concrete slabs with Fabsec steel beams in composite construction has had little research conducted in this area. The main purpose of the research is to develop an understanding into the behaviour of this form of construction and to demonstrate the advantages of using Fabsec …

Behavior and Strength of Welded Stud Shear Connectors
… has shown that the American Institute of Steel Construction (AISC) specification equations for shear stud strength are unconservative for studs placed in deck with ribs transverse to the steel beam. Twenty-four solid slab push-out tests, 93 composite slab push-out tests, and bare stud …

Crashworthiness of Side Impact Beams
… out into the crashworthiness of side impact beams. Two specific beams were investigated: a commercially used steel beam and a prospective composite beam made from a glass fibre weave within a polypropylene matrix. The components were simply supported and were subjected to quasi-static and …

Behaviours of steel connections with unfitted stiffeners
Steel beam-to-column connections are fundamental to the structural integrity and safety of steel-framed buildings. A critical issue arises when gaps exist between stiffeners and connected elements, referred to as unfitted stiffeners, which introduce uncertainties in the load-bearing capacity and …

Modelling and analysis of composite structures with semi-rigid connections
… this thesis involve concrete slabs with profiled steel sheeting supported by steel beams. The composite interaction is realized by providing shear connectors welded to the top flange of the steel beams. The columns are normally noncomposite. The steel beam-to column connections are either designed …

Vibration characteristics of joist and joist-girder members
With the development of lightweight steel beam and steel joist-concrete slab floor systems, floor vibration problems are becoming more and more prevalent. This paper presents the experimental and analytical study of the vibration characteristics of steel joist and joist-girder members. Three …

Fatigue Performance and Shear Demand Distributions of Clustered Shear Connectors in Composite Bridge Girders
… assumes uniform shear flow demands at the steel-concrete interface of composite bridge girders. As stud pitch increases to beyond 24 in or as studs become clustered to account for pre-cast concrete decks, this assumed shear demand distribution may be unrepresentative. Understanding shear …

Investigation of several aspects of the vibration characteristics of steel member-supported floors
… influencing the vibration characteristics of steel member supported floors were investigated. The four aspects are: 1) the number of tee-beams effective in resisting a heel-drop impact for steel joist and steel beam-concrete slab floors, 2) the effective moment of inertia of steel joist and …

Dynamic Shear Bands in Metals under High Strain Rates
… in capturing the mechanical behavior of steel alloy under different temperatures and strain rates, and therefore is used in the finite element analysis. Generally in finite element analysis, a finer mesh will yield results that are more accurate, but on the other hand will increase the …

Rapid Condition Assessment of Bridges By Falling Weight Deflectometer
… Pony Truss and a modern concrete deck on rolled steel beam bridge. Two full tests were performed on these structures with a hand held impact hammer and a falling weight deflectometer as sources for excitation. The advantage of using a FWD is that many transportation agencies already use these …

Examination of the application and limitations of structural mode extraction via force apportionment
… is illustrated on a 24 in. x 1.5 in. x 0.375 in. steel beam. The fourth bending mode is to be separated from the first torsional mode which is 26 Hz below the bending mode. The apportioned forces are applied and laser scans are acquired of the "modal" response. The laser allows detailed …

Lateral load distribution for steel beams supporting an FRP panel.
… when determining how much load a longitudinal beam supporting a bridge deck should be designed to hold. Depending on the deck material along with other variables, a different design distribution will be used. Since FRP is a relatively new material used for bridge design, there are no provisions …

Structural performance of perforated steel beams with novel web openings and with partial concrete encasement
… and load carrying capacities of classes of steel beam structures with various shapes of web openings. A comprehensive investigation on non-composite and partially concrete encased perforated steel Isections with large web openings positioned along the centre-line of the beams was undertaken. …

Finite element modelling of shear connection for steel-concrete composite girders
… modelling the structural behaviour of composite steel-solid slab concrete and steel-precast hollow core slab girders. A finite element model has been developed for the analysis of each type. The models took into account the non-linear behaviour of concrete slab, steel beam and shear connectors. …
