摘要:
对比研究了构建能力谱曲线的2种方法,即ATC-40中的能力谱方法和基于能量的增量位移方法,并利用强度折减系数-延性系数-线性周期关系构建了需求谱曲线; 以带梁式转换层的框支剪力墙结构为例,分析了改进方法应用于此类复杂高层建筑的可行性。结果表明:2种方法得到的能力谱曲线比较吻合,利用改进的能力谱方法得到的能力谱曲线更为平滑且稳定,确定的目标位移小于ATC-40中能力谱方法确定的目标位移,振型模式侧向荷载下的目标位移稍大于振型分解SRSS模式侧向荷载下的目标位移。
Abstract:
Two methods of building capacity spectrum curves were comparatively analyzed, e.g., ATC-40 capacity spectrum method and the energy-based incremental displacement method. Based on the relationships between strength reduction factor, ductility coefficient and linear period respectively, the two methods of building demand spectrum curves were proposed. Then, the methods were applied to a frame-supported shear-wall structure with beam transfer story to investigate their feasibilities in complex high-rise buildings. The results show that capacity spectrum curves from the two methods are similar; however, improved capacity spectrum method usually can obtain more smooth and stable curves. At the same time, the target displacement from improved capacity spectrum method is less than that of ATC-40 capacity spectrum method, and the target displacement from fundamental mode shape patterns is less than that of mode composition SRSS patterns.
