摘要
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 has significant effect on the seismic behavior of prefabricated reinforced concrete beamcolumn joints. In order to study its mechanical properties,the experimental studies were conducted on the connection joints under quasi-static loading. Numerical models were established by the software ABAQUS,and validate by the experimental results. Moreover,in order to further understand the behavior of connection joints,the parameter analysis was conducted to investigate the effect of flange plate thickness,rib length,ribbed slab thickness on the mechanical properties of connection joints. Finally a design method for this kind of connection joints was proposed.
