摘　　要：为了研究楼面梁与剪力墙平面外连接节点构造措施是否合理经济,结合具体工程,应用等值线(有限元)软件,分析钢筋混凝土剪力墙平面外在①无构造措施,②按规范设置暗柱,③梁端按简支3种情况下的应力及配筋。分析表明,墙在梁端弯矩作用下呈现梁顶、梁底应力集中后扩散现象;设置暗柱可以减少应力,暗柱通高设置并不能改变应力集中后扩散现象;仅配置构造钢筋的梁端对墙影响较小。综上提出一种新的处理方法:墙平面外搭梁局部附加钢筋做法。In order to study whether the out-of-plane connection nodes of floor beams and shear walls are reasonable and economical,combined with specific projects,the contour(finite element)software is applied to analyse the stress and reinforcement of the out-of-plane reinforced concrete shear walls in①no structural measures,②setting up dark columns according to specifications,and③the beam ends according to the simple support in three cases.The analysis shows that the wall presents the phenomenon of stress concentration and spreading at the top and bottom of the beam under the action of bending moment at the end of the beam;the setting of concealed columns can reduce the stress,and the setting of concealed columns through the height can not change the phenomenon of stress concentration and spreading;the beam end configured with structural reinforcement only has less influence on the wall.In summary,a new treatment method is proposed:the practice of local additional reinforcement of beams outside the wall plane.
