Abstract

Joint Conference Proceedings. 7th International Conference on Urban Earthquake Engineering. 5th International Conference on Earthquake Engineering. An efficient structural system for tall building construction to resist earthquake loads consists of RC shear walls connected by reinforced concrete coupling beams. Understanding of the load-deformation characteristics is essential to modeling the overall system response to seismic loading. Modeling studies are performed to evaluate the effectiveness of current modeling approaches with respect to key performance parameters, including effective elastic stiffness, ductility, and residual strength. As well, most of the experimental work that has been performed on coupling beams has been on specimens at less than full-scale. The impact of this scaling effect on the full-scale models is presented and shown to be potentially significant on the expected ductility of the member. A brief summary of simplified modeling techniques using commercially available software is presented to provide practical applications for design engineers. Results indicate that these simple modeling approaches reasonably capture measured force versus deformation behavior.
