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 wall is applied to the reinforced concrete frame structure, and the connection structure of the buckling restrained steel plate wall and the concrete structure is proposed. Based on the loading tests of two single-span two-story model structures, the lateral resistance performance of concrete frame-buckling restrained steel plate wall structure is studied, including the stress process, failure mode, failure mechanism, lateral stiffness, yield capacity and ductility Wait. The results show that the flexural-restrained steel plate wall structure of concrete frame has good lateral resistance performance. The buckling restrained steel plate wall effectively improves the lateral stiffness, yield capacity, ductility and redundancy of the reinforced concrete frame structure. The lateral stiffness and yield strength of the structure are calculated by theoretical method, and the results are basically close to the experimental values. The finite element method was used to simulate the stress process of the structure. The comparison with the experimental results shows that the finite element model and analytical method can simulate the force of the test model and can be used for further parameter analysis of the structure.
