| 摘 要： | 在半刚接框架-钢板剪力墙新型结构体系研究的基础上，采用ANSYS程序分析了不同墙体形式下结构的承载力、应力和变形发展历程，分析对比节点铰接、刚接、半刚接三种连接形式对钢板剪力墙结构承载力的影响。结果表明：设置加劲肋后，结构的屈服荷载提高约20%，极限承载力提高约10%。对于抗弯框架-钢板剪力墙结构，梁柱通过刚性连接与钢板墙组合，为双重抗侧力体系，节点刚接比铰接极限承载力提高约15%左右；节点半刚接和铰接极限承载力比较接近，相差仅在5%左右，为单重抗侧力体系。研究为该新型结构体系的工程应用和理论分析提供依据。

| Abstract: | Based on the study of a new semi-rigid composite frame with a steel-plate shear wall system, the structural bearing capacity of different wall forms, the stress and deformation development history are analyze using ANSYS program, and the effects on the bearing capacity of a hinged connection, a rigid connection and a semi-rigid connection are compared. The results show that the yield limitation of the frame is increased about 20%, and the ultimate bearing capacity is increased about 10% after setting stiffeners. For a bending-frame steel-plate shear-wall structure, the beam and the column are combined through the rigid connection with wall to form a double lateral force resisting system, and the ultimate bearing capacity of a rigid node is increased about 15% than that of a hinged one. There is about 5% difference for the ultimate bearing capacity between a semi rigid node and a hinged one, which is only a single lateral force resisting system. The research provides a basis for the new structural system and its theoretical analysis. |
