基于耦连比的摇摆柱-混合连肢墙结构延性设计方法及非线性分析

在现有摇摆柱-混合连肢墙结构概念的基础上，根据连续连杆法，推导了摇摆柱-混合连肢墙结构的耦连比估算方法，确定整体失效模式，提出基于耦连比的延性设计方法。将该结构模型应用于ABAQUS程序中分析了不同耦连比的摇摆柱-混合连肢墙结构在往复荷载作用下的力学行为。算例分析结果表明:推荐设计方法能保证结构预期失效模式的出现，墙肢底部损伤情况相比于普通混合连肢墙结构得到改善，同时预期耦连比对该结构延性性能和抗震性能有重要影响。

Ductility design method and nonlinear analysis of hybrid coupled wall system with leaning column based on coupling ratio

According to the concept of hybrid coupled wall system with leaning column, the estimation method of coupling ratio(CR) was deducedbased on the continuous connecting rod method, the whole failure mode was determined, and the ductility design method based on the coupling ratio was proposed. The hybrid coupled wall system with leaning column was applied in ABAQUS to analyze the mechanic behavior of structure with different CR under cyclic load. The example analysis results show that the recommended method can guarantee development of the target yielding mechanism,the damage at the bottom of the wall is improved compared with common hybrid coupled wall system, and the CR has an important influence onthe ductility and seismic performance of the structure.
