摘　　要：以北京LG大厦为背景,针对钢桁架与混凝土墙体之间的单剪板连接进行了大量有限元模拟分析 发 现约束弯矩的大小和很多因素有关,如节点板的厚度、螺栓直径、钢梁(钢桁架)跨度以及钢桁架高度等 并 根据分析结果拟合得到了适用于钢桁架与混凝土墙体之间连接约束弯矩的计算公式．Single - shear - plate connection is usually considered as pin connection in the design of SRC composite structure. In fact, restraining moment exists in the connection. Up to now, research is limted at connection between steel plate girder and RC shear wall. Considering Beijing LG Tower design as an example, finite element analyses of single - shear - plate connection between steel truss and RC core wall are carried out. Results show that the restraining moment are related to many factors, such as piate thickness, bolt diameter, span and height of steel truss etc. Based on analysis results, formula for the calculation of restraining moment of single - shear - plate connection between steel truss and RC core wall is derived.
