摘要

摘要: 为探讨钢结构梁柱半刚性节点三参数幂函数弯矩-转角曲线形状系数的精准性,采用有限元软件ANSYS对其进行仿真分析。针对外伸端板半刚性连接典型节点,分别建立了有限元实体模型和组件法的三参数幂函数模型,与试验结果进行验证,并通过有限元实体模型和组件法-三参数幂函数模型,基于韦伯分布,拟合了外伸端板半刚性连接形状系数的实用计算公式。结果表明:基于韦伯分布建立的外伸端板半刚性连接节点的形状系数计算公式,与已有计算公式比较,具有更高的精度;通过赋予Combin 39单元由组件法-三参数幂函数获得的弯矩-转角曲线建立有限元简化模型来进行设计,不仅能较为精准地模拟节点的性能,而且相对于有限元实体模型更为简便,便于在实际工程中应用,为设计钢结构梁柱非线性半刚性节点提供可靠的参考和依据。

Abstract: In order to discuss the accuracy of the shape factor of the three-parameter power function moment-rotation curves of semi-rigid steel beam-column joints, the finite element software ANSYS was used to simulate and analyze. The finite element solid model and the three-parameter power function model based on the component method were established respectively for the typical semi-rigid joints of the extended end plate, which were verified with the test results. Based on the Weber distribution, the practical calculation formula of the shape factor of the semi-rigid connection of the extended end plate was fitted through the finite element solid model and the three-parameter power function model based on the component method. The results showed that the formula for calculating the shape factor of semi-rigid connections with extended end plates based on Weber distribution was more accurate than the existing formula; by giving COMBIN39 element a simplified finite element model of bending moment-rotation curves obtained from the three parameter power function based on the comporent method, the design could not only accurately simulate the mechanical properties of the joint, but also could be simpler than the finite element solid model, which is convenient for application in practical projects, and provided a reliable reference and basis for the design of nonlinear semi-rigid joints of steel structure beams and columns.
