[摘要]  剪力墙连梁常常出现超筋和受剪承载力难满足等问题。双连梁在一定程度上解决了这些问题，但存在施工麻烦、刚度降低等弊端，所以研究合理的连梁形式是一个非常有意义的课题。随着高强钢筋高强混凝土的推广越来越广泛，其在剪力墙结构中大量使用势在必行。因此把高强钢筋高强混凝土和连梁形式结合起来，建立几种连梁形式，分析它们在弹性阶段以及弹塑性阶段的受力特征，将会给剪力墙连梁的设计带来新的突破。本文首先建立与试验构件相同的ABAQUS有限元模型，有限元结果与试验结果吻合较好。依据试验建立了五个连梁形式不同的有限元模型，对比弹塑性分析结果，得出既能解决连梁超筋问题，又便于施工的连梁形式。

Abstract: The amount of reinforcement in coupling beam is always beyond the ruled ratio and the resisting shear is difficult to achieve. Dual coupling beam can solve those problems to a certain extent but produces new disadvantages such as cumbersome construction process and stiffness reduced. So researching reasonable coupling beam forms is a very important subject. As high strength steel and high strength concrete are promoted more widely, they are sure used in large quantities in the shear wall structure. Combined high strength steel and high strength concrete along with coupling beam forms, several models are established, and through analyzing mechanical characteristics in elastic and elastic-plastic stage, new breakthrough for coupling beam design will be brought. In this paper, a finite element model based on the experimental model is built firstly, and the post-processing model results are in good agreement with the test results. Secondly five finite element models with different coupling beam forms are built. Through analyzing the five models, one of them stands out, which not only solves the beyond ruled reinforcement ratio problem, but also brings convenient to construction.
