摘要
对北京国贸大厦进行了罕遇大震下的弹塑性时程分析,指出了钢-混凝土筒混合结构的地震反应特点,并对此类结构设计时的位移控制、高宽比、塑性铰机制和加强层设置等提出了一些设想.
Base on the plastic and elastic duration analyses to China World Tower in rare earthquake, the issue shows the characteristics of earthquake reaction of steel-concrete mixture tubular structure. Some considerations are also delivered, such as displacement control, ratio of height to width, plastic hinges mechanics and strengthening layer setup etc.
