[摘要] 剪力墻連梁常常出現(xiàn)超筋和受剪承載力難滿足等問題。雙連梁在一定程度上解決了這些問題，但存在施工麻煩、剛度降低等弊端，所以研究合理的連梁形式是一個非常有意義的課題。隨著高強鋼筋高強混凝土的推廣越來越廣泛，其在剪力墻結(jié)構(gòu)中大量使用勢在必行。因此把高強鋼筋高強混凝土和連梁形式結(jié)合起來，建立幾種連梁形式，分析它們在彈性階段以及彈塑性階段的受力特征，將會給剪力墻連梁的設(shè)計帶來新的突破。本文首先建立與試驗構(gòu)件相同的ABAQUS有限元模型，有限元結(jié)果與試驗結(jié)果吻合較好。依據(jù)試驗建立了五個連梁形式不同的有限元模型，對比彈塑性分析結(jié)果，得出既能解決連梁超筋問題，又便于施工的連梁形式。

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.
Keyword: the form of coupling beam; ABAQUS finite element analysis; the load displacement curve
