Steel plate shear walls (SPSWs) are a robust lateral load resistance structure because of their high ductility and efficient energy dissipation when subjected to seismic loads. This research investigates the performance an innovative infill web strip (IWS-SPSW) typical unstiffened steel wall (USPSW). As result, two 1:3 scale specimens IWS-SPSW USPSW with single story bay were built cyclic loadi...

This series of experiments aims to characterize the cyclic behavior of cold-formed steel (CFS) stud-to-sheathing connections. This connection provides the key energy dissipating behavior in wood sheathed CFS shear walls, and provides bracing to the studs under gravity and out-of-plane loads. A simple testing rig is developed consisting of two CFS lipped channels facing toe-to-toe connected on t...

Composite Plate Shear Walls−Concrete Filled (C-PSW/CF) are an innovative seismic force resisting system recently adapted for building applications. The walls consist of parallel steel faceplates connected with tie bars and filled concrete. This paper summarizes the results a recent FEMA P695 study completed to verify design parameters uncoupled C-PSW/CFs rectangular flange plate boundary elemen...

the effect of steel plate thickness on the repair effectiveness of rc beam is presented in this paper. a total of four beams were tested, one beam repaired by cfrp with a thickness of 1.2 mm and used as a control beam, and three beams repaired by a steel plate. steel plates with a thickness of 2 mm, 3 mm, and 4 mm were used in repairing the beams. the maximum load-carrying capacity, deflection ...

The objective of this paper is to explore the potential strength and serviceability implications of metallic foams, specifically steel foam, utilized as a thin-walled channel structural member. A typical advantage sought in the selection of a thin-walled member is minimal weight. However, the stability of the thin walls and the related limit states constrains the extent to which weight minimiza...
