After the 1995 Hanshin-Awaji Earthquake, large efforts have been made to minimize damage of buildings under earthquakes in order to keep structures functional in addition to securing life safely. However, making structures behave elastically under the seismic loading is costly and optimized elasto-plastic behavior is considered the most favorable method from the economic viewpoint. In this paper, the corrugated steel shear walls are used in RC frame structures to resist the seismic lateral force with high stiffness for small earthquakes, and with large deformation capacity for larger earthquakes. An experiment was conducted to study their seismic performance. The specimens were 1/3 scale and made of a portal RC frame with a corrugated steel plate shear wall. The amount of anchoring studs of corrugated steel plate was varied so that H2V2 satisfied the design criteria and H1V1 had half amount. Both specimens showed good performance in terms of load carrying capacity, equivalent damping ratio, and etc. until the peak load was reached. Degradation of lateral load carrying capacity of H2V2 after the peak was acceptable but that of H1V1 needs special care for practical design.
