摘要
分别按设防烈度为6度、7度、7度(0.15g)、8度和8度(0.30g)时规范最低要求设计了5个高层框架-剪力墙结构,作为分析实例,采用增量动力分析方法(IDA)初步研究了其在大震作用下的抗倒塌能力。得到以下结论:构件形成塑性铰或破坏的顺序符合概念设计思想,满足多道抗震设防的理念;框架-剪力墙结构具有明显的屈服点;符合规范要求的高层框架-剪力墙结构基本满足"大震不倒"的设防目标。
Taking 5 tall frame-shear wall structures which were designed according to minimum requirements of fortification intensity 6,7,7（0.15g）,8 and 8（0.3g） respectively in design code as examples,collapse resistant capability was studied preliminarily under rare earthquake by incremental dynamic analysis method.Conclusions have been reached as follows： the order of structural member′s plastic development（plastic hinge or collapse） fits the conception of displacement-based seismic design and multi-line seismic resistance,frame-shear wall structures have clear yielding point,structures which conform to design code can basically satisfy the fortification objectives of no-collapse under rare earthquake.
