Novel flange belt inner sleeve splicing joint of steel pipe column and mechanical property analysis method
The invention relates to the technical field of assembly type steel structures, in particular to a novel flange inner sleeve splicing joint of a steel pipe column and a mechanical property analysis method. The method comprises the steps of (1) determining the structure of the flange inner sleeve splicing joint of the steel pipe column, the size of a flange inner sleeve and the specification and number of bolts; 2) establishing a steel pipe column flange inner sleeve splicing node model by adopting a finite element method; (3) performing variable parameter analysis on the steel pipe column splicing joints, discussing the influence of different parameter values on the overall bearing capacity and hysteresis performance of the joints and components, and generating a reasonable value range; and 4) performing comparative analysis on the mechanical properties of the novel flange belt inner sleeve splicing joint of the steel pipe column and the traditional joint. Bolt tension can be effectively reduced, and warping of the flange plate is restrained; the node is high in bearing capacity and good in ductility and hysteretic performance, and has the characteristics of high field assembly speed and high construction efficiency; the analysis method better verifies the feasibility of the novel node in engineering application.
本发明涉及装配式钢结构技术领域，涉及一种钢管柱新型法兰带内套筒拼接节点及力学性能分析方法，方法包括：1)、确定钢管柱法兰内套筒拼接节点构造，法兰内套筒尺寸、螺栓规格和数目；2)、采用有限元方法建立钢管柱法兰内套筒拼接节点模型；3)、通过对钢管柱拼接节点进行变参数分析，讨论不同参数取值对节点和构件整体的承载力和滞回性能的影响，并给出合理的取值范围；4)、对钢管柱新型法兰带内套筒拼接节点和传统节点力学性能进行对比分析。本发明能有效降低螺栓拉力，抑制法兰板的翘曲；节点承载力高、延性和滞回性能好，同时有现场装配速度快和施工效率高的特点；分析方法较佳地验证了新型节点在工程应用中的可行性。
