摘　　要：某工业生产车间内部含多处夹层,利用通用有限元软件SAP2000对其进行建模和计算,结果表明夹层与主结构连接节点的选型不仅影响到整个结构的扭转振动效应,同时对主刚架内力以及稳定性能的影响也很大,而且不能简单的认为铰接好或者是固接好,连接节点型式的选取还受制于夹层自身所承受荷载的大小以及内部夹层的分布。One food ingredients workshop in Lianyungang includes many mezzanines,the structure modeling and calculation is finished by F-EA software sap2000,and it turns out that the type selection of connections not only concerns the torsional vibration effect of structure,but also has a great influence on the internal force and stability of main structure,hinge joint is better or rigid connection is better are all not right,and the type selection of the connections depends on both the value of the load acting on the mezzanine and the distribution of mezzanines.
