The Semi-analytical Testing Method of Rigid Connection Joint in the prestressed steel structure

本文通过半解析测试方法获取预应力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。并分析预应力对节点的影响。

Using a semi-analytical method to study the semi-rigid characteristics of beam-to-column connections of the prestressed steel structures.On the basis of the theoretical analysis of semi-rigid connections,a calculation model of the beam-to-column connection rigidity is derived.By introducing the actual load and the displacement values at at the end of the beam,an effective semi-analytical method for calculation the connection rigidity of steel structures is presented.And analyzes the effects of prestress to the connection joint.
