作者在文献[1]中提出了半刚接钢框架内填RC墙结构(简称PSRCW)的两阶段抗震设计方法。该文用此方法设计了1榀6层3跨PSRCW结构,采用塑性机构法、Pushover分析方法及弹塑性时程法对设计算例进行了地震反应分析,评估了算例结构的抗震性能。结果表明:塑性机构法同采用组合斜压板带模型所得到的极限水平承载力相近,结构的整体超强系数为3.34,具有较大的抗侧能力和超强性能。在多遇及罕遇地震下结构的层间侧移比满足现行抗震规范要求,结构具有良好的抗震性能,进一步证明了PSRCW结构的两阶段抗震设计方法的合理性。
In [1], the authors proposed a two-stage seismic design method for RC RC walls filled with semi-rigid welded steel frame (PSRCW). In this paper, 1 榀 6 layers and 3 span PSRCW structures are designed by this method. The seismic response analysis of the design example is carried out by using the plastic mechanism method, pushover analysis method and elastoplastic time-history method, and the seismic performance of the example structure is evaluated. The results show that the plastic mechanism method is similar to the ultimate horizontal bearing capacity obtained by the model of combined barocline slab, and the overall super strength coefficient of the structure is 3.34, which has greater lateral resistance and superior performance. The result shows that the structure has good anti-seismic performance under the conditions of frequent and rare earthquakes, which further proves the rationality of the two-stage seismic design method of PSRCW structure.
