［摘要］為研究鋼筋混凝土框架-鋼板剪力墻抗震性能，對一榀單跨兩層的鋼筋混凝土純框架和一榀單跨兩層的鋼筋混凝土框架-鋼板剪力墻進行低周往復(fù)加載試驗，比較兩者的破壞形態(tài)并分析原因。研究結(jié)果表明：鋼筋混凝土框架-鋼板剪力墻的承載力較鋼筋混凝土純框架提高77-2％，初始剛度為鋼筋混凝土純框架的2-67倍；非加載端梁、柱應(yīng)變值較大，加鋼板的混凝土框架節(jié)點轉(zhuǎn)角變化量不大，破壞也相對較輕。建議通過加鋼板來提高鋼筋混凝土框架的承載性能及抗震性能。

Abstract:In order to study the seismic performance of reinforced concrete frame-steel plate shear wall， a low-cycle load test was carried out on a reinforced concrete frame with a single span two lagers and a reinforced concrete frame-steel plate shear wall with a single span two layers. The from and reason of the failure of the two structures was analyzed. The results show that the load-bearing capacity of reinforced concrete frame-steel plate shear wall is 77-2% higher than that of reinforced concrete frame, and the initial stiffness is 2-67 times that of reinforced concrete frame. The non-loading end beam and the column strain value are larger, the change of the rotation angle of the concrete frame node with steel plate is small, and the damage is relatively light. It is recommended to increase the bearing performance and seismic performance of reinforced concrete frame by adding steel plate.
Keywords:reinforced concrete frame; steel plate shear wall; seismic performance; rotation angle
