中文摘要：

为了研究装配式钢框架结构柱与柱螺栓连接半刚性节点对纯框架整体结构的影响，采用ANSYS有限元分析软件，对8层2跨钢框架整体结构进行了分析，研究了柱与柱半刚性连接钢框架在风荷载作用下的弹塑性性能，得到半刚性柱与柱连接节点对整体结构力学性能的影响规律。由于柱与柱半刚性连接节点的存在，钢框架在变形性能比刚性连接钢框架有一定提高，同时其侧向位移有所增大。对于柱与柱半刚性连接钢框架，由于柱与柱连接节点的柔性影响，会增大整体框架的梁端弯矩。

英文摘要：

To study the effect of column-column flange bolt semi-rigid connection in prefabricated steel frame on the overall frame structures, two-span and 8-story steel frame structure were analyzed by the ANSYS software. The elasticplastic performance of the semi-rigid connected steel frame and the effect of the semi-rigid connection on the overall frame structure were obtained by the FEA. As a result of semi-rigid connection, the deformation performance of the semi-rigid connected steel frame was higher than that of the rigid connected steel frame, and the lateral displacement was enlarged. For semi-rigid connected steel frame, the beam-end bending moment of the overall framework increased because of the flexibility of the column-column flange connection.
