Abstract: Load-bearing cold-formed steel (CFS) walls sheathed with double layers of gypsum plasterboard on both sides have demonstrated good fire resistance and attracted increasing interest for use in mid-rise CFS structures. As the main connection method, screw connections between CFS and gypsum sheathing play an important role in both the structural design and fire resistance of this wall sy...

in this paper, nonlinear behavior of composite steel plate shear wall systems, in which steel infill plate is strengthened by fiber reinforced polymer (frp) layers, are experimentally investigated. tests are designed to evaluate the effect of glass-frp layers, layers number of gfrp and orientation of gfrp layers on the stiffness, shear strength, cumulative dissipated energy and other seismic pa...

Pre-stressed steel-concrete composite beams are widely used in bridges around the world. Loads during service life of may cause failure form fracture studs near ends bridge girders. The effect stud on residual static capacity and fatigue girders is not well investigated. Therefore, this study presents numerical investigations into effects progressive shear connectors performance remaining post-...
