Thanks to the superiority in rapid and economic construction and the cooperativity with realization of building function, modular construction provides an excellent scheme for conventional on-site buildings with repetitive units. Corrugated steel plate is a widely adopted and efficient lateral force resisting component in modular construction. The extensive use is motivated by the large initial stiffness, high level of energy dissipation capacity and the ability to accommodate openings. However, it is lack of information regarding the detailed seismic behavior of corrugated steel plate shear walls (CSPSWs), particularly walls with openings. In this paper, five full-scale quasi-static tests on CSPSWs, with and without opening, were carried out to evaluate their seismic performance. The results reveal that although initial stiffness of CSPSWs is significantly reduced due to the opening, the ultimate strength and energy dissipation ratio are averagely 14.4% and 28.7% higher than the CSPSW without opening. Two different lateral-force resistance mechanisms are observed and discussed in details. Meanwhile, several design recommendations are also given for CSPSWs, which will provide useful references for the application of CSPSWs in seismic region. (C) 2017 Elsevier Ltd. All rights reserved.
