摘　　要：利用ALGOR有限元软件,分析了不同节点连接型式的多层钢框架-混凝土筒结构体系在水平地震作用下的整体受力性能。研究表明:不同节点连接方式对结构体系的动力特性影响较小;最大水平位移和层间位移均能满足相应的要求;大部分水平地震剪力由混凝土筒承担;当梁柱采用半刚性连接时,钢柱分配到的水平地震剪力小于梁柱刚接时,因此能更好发挥混凝土筒的抗侧力性能。这些研究结果为多层钢框架-混凝土筒的结构设计提供一定的理论依据。Using a finite element software—ALGOR, this paper has analyzed the multi-story steel frame-concrete tube structure with different connection types of nodes and the holistic resistant behavior under horizontal dynamic force. The conclusions indicate: different connection types of nodes has less influence on the dynamic behavior of structural system; the maximum horizontal displacement and the relative displacement between adjacent stories both meet the corresponding demands; concrete tube bears most horizontal seismic shear force; when the beam-column has semi-rigid connection, the steel column’s horizontal seismic force is less than that of the beam-column with rigid connection.
