摘　　要：近些年剪力墙住宅愈发增多,研究提出了一种薄弱位置的节点设计方案,该节点可用于剪力墙结构中部分现浇混凝土保温复合填充墙与剪力墙、梁等结构构件的弱连接,同时还可利用土木结构非线性软件进行有限元计算分析。结果表明:通过对比弱连接节点及结构构件的剪应力可知,混凝土现浇外墙与周边结构构件的弱连接剪应力远大于主体混凝土梁在对应工况下的剪应力,该弱连接节点可以满足先于主体混凝土梁破坏的要求,故节点构造切实可行。In recent years,there has been an increasing number of shear wall residential buildings,and research has proposed a node design scheme for weak positions.This node can be used for weak connections between partially cast-in-place concrete insulation composite infill walls and structural components such as shear walls and beams in shear wall structures.At the same time,non-linear civil structural software can also be used for finite element calculation and analysis.The analysis results show that by comparing the shear stress of weak connection nodes and structural components,it can be seen that the shear stress of weak connection between the cast-in-place concrete exterior wall and surrounding structural components is much greater than the shear stress of the main concrete beam under corresponding working conditions.This weak connection node can meet the requirement of failure before the main concrete beam,so the node construction is practical and feasible.
