In this study seismic performance of rectangular reinforced concrete staggered wall system(SWS) structures with middle corridor were evaluated. To this end, 6, 12, and 18-story SWS structural models were designed and were analyzed by pushover analysis to observe the force-displacement relationship up to failure and the location of plastic deformation. Also response modification factors were computed based on the overstrength and the ductility capacities obtained from capacity envelopes. The analysis results showed that plastic hinges formed first at connection beams located between two staggered walls and the structures failed by formation of weak stories. When the bending rigidity of the connection beams increased up to 100%, the overstrength increased by only about 25%. When the reinforcement ratio was increased by 50%, the overstrength increased by about 40%. The replacement of the RC connection beams with steel box beams resulted in superior performance of the structures with reduced beam depth. The response modification factors ranged between about 4.0 and 6.0 with the average value around 5.0. Based on these observation it was concluded that the staggered wall systems with a middle corridor have enough capacity to resist the design seismic load.
