Seismic Performance Behavior of Cold-Formed Steel Wall Panels by Quasi-static Tests and Incremental Dynamic Analyses

Abstract

Domestic houses built of cold-formed steel (CFS) are typically supported laterally by wall panels that are made of braced steel studs. The behavior of those panels under cyclic strain reversals in an earthquake is too complex to analyse and is best evaluated by physical experimentation. Dynamic testings of full-scale wall specimens on a shaker table have been undertaken in previous studies but repeating those tests for different design configurations and base excitations can be very costly. This article presents seismic performance behavior of CFS wall panels based on monotonic, and cyclic, quasi-static tests followed by incremental dynamic analyses (IDA).
