Abstract

The study presented herein is concerned with assessing the influence of connector elements on the behaviour of finite element models of high capacity cold-formed steel (CFS) shear walls. Recently, CFS shear walls have been used as an economic and light-weight seismic force resisting system (SFRS) in North America, however their applications are limited to mid-rise buildings. To push the state-of-the art, a preliminary testing programme of an innovative, higher-capacity CFS shear wall is conducted. The testing programme consists of monotonic and cyclic tests as well as screw connection assembly tests in double shear. Furthermore, explicit shell finite element models of the shear walls were developed and calibrated with the experimental results. Finally, a parametric study on the type of connector element was carried out to assess the behaviour of the wall. The results indicate that representing the screw-fastened connections using three uncoupled springs gave the best numerical estimate.
