Reinforced concrete core walls are used commonly in modern building construction as the primary lateral-load resisting system. Common core wall con gurations include solid walls in one direction and walls with openings in the orthogonal direction to access ele-vators or to meet architectural requirements. Therefore, in the orthogonal direction, the walls are typically coupled together by reinforced concrete \coupling" beams. A signi - cant amount of research has focused on the design of coupling beams to ensure that they exhibit ductile response through multiple cycles to large drift demands. However, only a few research studies have investigated the seismic behavior of coupled wall systems, and most of these previous studies have considered coupled-walls in low-rise structures. Most
coupled walls are used in elevator cores, which are more typical in mid- to high-rise con- struction. A research study was undertaken by faculty and students at the Universities of Washington and Illinois to speci cally investigate this category of structural system. The advanced testing capabilities of the NEES University of Illinois at Urbana-Champaign (UIUC) testing facility permitted unique experimental simulation of this system.
The coupled-wall test specimen simulated the bottom three stories of a ten-story building in a region of high seismicity designed with typical geometry and reinforcement.
