Test of a Steel Plate Shear Wall with Partially Encased Composite Columns and RBS Frame Connections
Publication: Journal of Structural Engineering
Volume 144, Issue 2
Abstract
A large-scale steel plate shear wall with partially encased composite (PEC) columns and reduced beam section (RBS) frame connections was tested at the University of Alberta to investigate the behavior of the system and quantify some key characteristics related to seismic design of this system. The use of RBS connections was intended to reduce the demand on the beam-to-column connection and obtain improved seismic performance. Subjected to quasi-static cyclic load until severe damage was observed, the specimen showed desirable characteristics such as high elastic lateral stiffness, ductility, and energy dissipation capacity. The use of RBS frame connections was proven to be a viable option to improve the seismic performance of these walls. The test observations indicated that the detailing of the PEC columns played an important role in improving the seismic performance of the specimen. Several design and detailing recommendations have been made based on the observations during this test and previous experimental studies.
