对空间钢结构和组合型半刚性节点进行试验以研究其性能。考虑半刚性节点从次轴向主轴加载的效应。对半刚性空间钢结构和组合外伸端板节点进行5个足尺试验。利用ANSYS构建三维有限元模型对其进行分析研究。对现有数值模型和试验结果进行对比,以验证模型的有效性。同时,通过在空间结构上采用梁单元模型来研究节点刚度,这一效应已经被前面的研究所证实。
Space steel structures and composite semi-rigid joints were tested to study their properties. Consider the effect of semi-rigid node loading from secondary axis to primary axis. Five full-scale tests were conducted on semi-rigid space steel and composite overhanging end plate joints. The use of ANSYS to build three-dimensional finite element model of its analysis. The existing numerical model and test results are compared to verify the validity of the model. At the same time, the effect of node stiffness has been confirmed by previous studies by using beam element models in the spatial structure.
