摘要

高层建筑结构失效演化过程的量化分析是实现基于性能抗震设计方法的关键步骤之一,为了得到斜交网格筒结构体系基于整体稳定的失效判别方法,基于连续化方法的体系变形分析,给出了斜交网格筒结构体系的初始等效抗侧刚度求解方法,并对体系的变形形态进行了探讨;通过整体稳定平衡分析得到斜交网格筒结构体系瞬时等效刚重比与结构响应的关系,并提出了基于瞬时等效刚重比变化的失效判别方法;通过对结构进行20条地震波罕遇地震作用下的弹塑性时程分析及斜交网格筒子结构模型试验,验证了该方法的正确性。

Abstract

Quantification of evolutionary process of structural failure is one of the critical steps when carrying out performance-based seismic design for high-ride structures. In order to establish invalidation discrimination of diagrid tube structures, the calculation method of initial equivalent lateral stiffness of diagrid tube structures based on continuous method of structural deformation analysis was proposed firstly, and the deformed shape of the structural was also discussed. Then method of failure discrimination based on instantaneous equivalent ratio of stiffness to weight was proposed through entire stable equilibrium analysis. Eventually, rare earthquake elastoplastic time-history response analysis and quasi-static test have been performed for verifying the proposed method.
