摘要
根据高层框架结构拟动力试验的P -Δ曲线 ,着重分析了极限位移中包含的各种成分 ,层间位移限值中不确定因素存在的原因及对结构垮塌破坏的影响。针对刚性设计和延性设计的特点 ,提出了增设抗震斜柱的设计思想。旨在实现基于位移的抗震设计 ,提高结构的抗震性能。
According to P-Δcurve of simulative dynamic test for tall frame structures, all kinds of elements in the ultimate displacement, uncertain factors in layer-to-layer displacement and destroying reasons are analyzed. Based on specificity from rigidity and ductility design, tentative ideas for adding to seismic skew column are proposed in order to realize displacement-based design and enhance seismic properties of structures.
