对变电站中高架柱与人字柱连接节点的受力性能进行了有限元研究。在对有限元分析结果验证后,通过改变节点处各类加劲板件的参数,对大量模型进行了非线性有限元分析,分析结果表明:高架柱与人字柱连接节点处加劲板及顶板厚度对节点性能影响很小;主要受力加劲板是否插入人字柱对节点性能影响很小,设计该节点时,可仅从人字柱局部变形要求考虑是否需要将主要受力加劲板插入人字柱。分析计算过程及结果可供实际工程参考。
The finite element analysis is carried out on the mechanical properties of the connecting nodes between the elevated columns and the studs in the substation. After verifying the results of finite element analysis, a large number of models were analyzed by nonlinear finite element method by changing the parameters of all kinds of stiffened plates at the node. The results show that the stiffener thickness and roof thickness The impact on the node performance is very small. Whether the main stiffened plate is inserted into the stile has little effect on the node performance. When designing the node, the deformation of the stile can be considered only if the main stiffened plate needs to be inserted into the herringbone column. Analysis and calculation process and results for the actual project reference.
