Assessing possible economic or operational benefits of class 3 webs without stiffeners vs class 4 webs with stiffeners in steel plate girders
… focuses mainly on optimisation for bending moment resistance. Shear capacities of the cross-sections were also computed and compared because shear forces share a close relationship with bending moments being a derivative of the moment. The idea was that upon exhausting the capacity of the …

Experimental and analytical study of the shear transfer in composite shallow cellular floor beams
… to investigate the load-slip behaviour and shear resistance of the shear connections under direct shear force. The failure mechanisms of the two forms of shear connections were extensively studied, which lead to the development of a design method for the composite action. The concrete infill …

An Algorithm and Methodology for Static Response Based Damage Detection in Structural Systems
… a new finite element that better models reduced moment resistance in connections. The new element is derived from elementary principles and is very well suited for optimization. The research attempts to utilize experimental test data whenever possible. When test data is not available, efforts are …

Effect of stressed skin action on the behaviour of cold-formed steel portal frames with non-linear flexible joints and top-hat purlins
… have been investigated by testing, as follows:1) Resistance and stiffness of bolted moment-connections. The bearing resistance and stiffness of the threaded bolt shank in single and double shear lapped connections were tested and compared against design recommendations.The existing methods for …

Seismic performance of an I-girder to inverted-T bent cap bridge connection
… regarding the seismic response and overall moment capacity of precast I-girder to inverted-T bent cap bridge connections for seismic applications. The current design practice, as outlined by Caltrans' Seismic Design Criteria, assumes that the connection between the precast I-girders and the …

Behaviour of unstiffened flush end plate beam-to-column connections in structural steelwork
End plate connections are extensively used as moment resistant connections between members in steel frame. Surveys of the English and Scottish Steelwork Industry clearly indicate that the flush end plate connection is the most popular type of beam-to-column connection in steel-framed structures. …

Investigating the Performance of Wood Portal Frames as Alternative Bracing Systems in Light-Frame Wood Buildings
… from the corner joint tests that the maximum moment resistance increased with the addition of metal straps or exterior sheathings. The test results also showed a significant increase in the moment capacity and rotational stiffness by replacing the Spruce-Pine Fir (SPF), header with the …

A study of the rotational behaviour of the bolted connections in the cold-formed steel purlin system
… on the dominant mechanism that provides the resistance to the rotation. Different formulas are used in different stages to determine the behaviour of the connection, boundary conditions, and magnitudes of bolt forces. The new model reflects well the true behaviour of the connections, and …

Development of the low damage self-centering Sliding Hinge Joint
… SCSHJ, the ring spring will partially develop moment resistance, store and release energy which improves self-centering, and reduce elastic strength losses through pre-stressing. The objective is to improve dynamic self-centering behaviour, taking shake-down of the building into account. The …

Development of a Mobility-Enabling Spinal Orthosis and Methods for Evaluating and Developing Spinal Orthoses on a Robotic Platform
… Load cells recorded the RTP-applied forces and moments as well as the forces and moments at the base of the lumbar spine. The START orthosis and a commercial spinal orthosis (The Orthotrac Pneumatic Vest) were tested for comparison on the RTP in a limited range of sagittal flexion (5°) and …
