摘　　要：将屈曲约束钢板墙用于钢筋混凝土框架结构,提出了屈曲约束钢板墙与混凝土结构的节点连接构造。通过2个单跨两层模型结构的加载试验,研究了混凝土框架-屈曲约束钢板墙结构的抗侧力性能,包括其受力过程、破坏形态、破坏机制、抗侧刚度、屈服承载力和延性等。研究结果表明:混凝土框架-屈曲约束钢板墙结构具有良好的抗侧力性能,屈曲约束钢板墙有效提高了钢筋混凝土框架结构的抗侧刚度、屈服承载力、延性和冗余度。利用理论方法计算了结构的抗侧刚度和屈服承载力,其结果与试验值基本接近。利用有限元方法对结构的受力过程进行了模拟,与试验结果的对比表明所建立的有限元模型及分析方法基本能够模拟试验模型的受力情况,可用于该类结构的进一步参数分析。The buckling restrained steel plate shear wall （BRSPSW） is used in reinforced concrete frame structure, and the joints connecting buckling restrained steel plate shear wall and concrete frame are presented. The loading test of two specimens with single span and two stories was conducted to study the lateral load resisting performance of reinforced concrete frame with buckling restrained steel plate shear wall, including the loading process, failure mode, failure mechanism, lateral stiffness, yield capacity and ductility. The test results indicate that reinforced concrete frame with buckling restrained steel plate shear wall has excellent lateral load resisting performance. Buckling restrained steel plate shear wall greatly enhances the lateral stiffness, yield capacity, ductility and redundancy of reinforced concrete frame structure. Furthermore, lateral stiffness and yield capacity of the test specimens were calculated using theoretical method, and has good agreement with test results. The finite element analysis was also conducted in order to predict the loading process of the test specimens. Comparison indicates that the finite element model and the analysis method in this paper can accurately simulate the loading behavior of the test specimens, and can be used in the parametric analysis of this kind of structure.
