高强螺栓型钢连接节点是影响装配式混凝土梁柱节点抗震性能的关键连接部分。对高强螺栓型钢连接节点进行低周反复荷载试验以考察其受力特性,利用有限元软件ABAQUS建立数值分析模型并与试验结果进行验证对比,进而利用有限元模型进行参数分析,研究法兰板厚度、肋板长度、肋板厚度等参数对螺栓型钢连接节点的受力性能的影响,同时给出了针对这种连接节点的设计方法。
High-strength bolt steel connection node is a key part of the connection that affects the seismic performance of the prefabricated concrete beam-column joints. The low-cycle repeated load test of high-strength bolt-type steel joint was carried out to investigate its stress characteristics. The numerical analysis model was established by finite element software ABAQUS and compared with the test results, and then the finite element model was used to analyze the parameters. , The length of the rib, the thickness of the rib and other parameters on the mechanical properties of the bolted steel connection node, and gives the design method for this connection node.
