| 摘 要： | 通过半解析测试方法获取钢结构梁柱连接节点的半刚性特性。在半刚性节点理论分析的基础上,导出了包含节点连接刚度的计算模型;然后通过结合已知的梁端实测荷载和位移试验值,给出了一种有效的求解节点刚度的半解析测试方法。该方法可以克服试验中直接测量节点转角的困难和精度误差,而且与有限元分析结果相比,其计算结果更符合实际真实解。数值算例结果表明,采用该文提供的半解析测试方法获取钢结构梁柱半刚性连接节点M-θ曲线是简单、有效和准确的。

| Abstract: | A semi-analytical method is provided to predict the behavior of beam-to-column semi-rigid connections of steel structures.A calculation formula of beam-to-column connection rigidity is derived firstly based on the theoretical analysis of semi-rigid connections.With the derived theoretical formula of connection rigidity and a series of experimentally measured values of loads and displacements at the end of beam,an effective semi-analytical method for the prediction of semi-rigid connection rigidity of steel ... |
