Due to architectural, mechanical and even structural considerations, in some cases there is need to create some openings in the composite steel shear walls. Presence of the openings can considerably affect the wall behavior. Therefore in this study, the effects of the opening on the behavior of composite steel shear walls are investigated. For this purpose, first an experimental specimen withou...

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...

Small-scale, instructional shake tables, such as the UCIST shake table, are used at many colleges and universities to provide educational and research experiences in seismic behavior of structural systems. This paper describes the development of a physical model and associated educational materials that demonstrate the seismic behavior of shear walls used in cold-formed steel (CFS) building sys...

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...

Conventional design of steel plate shear walls SPSWs assumes that 100% of the story shear is resisted by each infill panel. Following this approach, strength provided by the boundary frame moment resisting action, which provides the SPSW with overstrength, is neglected. While this design assumption has a positive impact on seismic performance of SPSWs, no analytical work has been done to quanti...

Bridges are built in a variety of locations, many of which are susceptible to multiple extreme hazards (earthquakes, vehicle collisions, tsunamis or storm surges, and blasts are considered in this research since they are present as a minimum for some locations). This underscores the need to develop an innovative design concept for bridges from a multi-hazard perspective in which all hazards and...
