| 摘 要： | 隔震器与填充墙对建筑抗震性能有很大作用。为了探究填充墙布置形式及填充材料和隔震器协同作用对钢筋混凝土框架结构动力特性及抗震性能的影响,采用等效斜撑理论,对3种不同填充墙布置形式与隔震器协同作用的抗震系统方案进行对比分析,研究发现顶层不布置填充墙与隔震器协同抗震系统钢筋混凝土框架结构的抗震性能最佳。在此系统上分析了不同填充材料对钢筋混凝土框架结构抗震性能的影响,结果表明,加气混凝土砌块填充墙的钢筋混凝土框架结构抗震性能最好。

| Abstract: | Vibration isolators and infill walls have great effects on the seismic performance of buildings. In order to explore the influence of the infill wall layout and material on the dynamic characteristics and seismic performance of the reinforced concrete (RC) frame structures, an equivalent model based on the equivalent brace theory was adopted to compare and analyze three anti-seismic system schemes of differing filled-wall arrangements with the cooperative work of a vibration isolator. It was found that the seismic performance of the RC frame structure is best with no infill wall on the top floor. On this basis, the effect of different filling materials on the seismic performance of RC frame structure was analyzed. The results showed that the seismic performance of the RC frame with aerated concrete block filled wall is best. |
