摘要
结合某大型铁路旅客站房高架候车厅楼盖结构,采用ADINA有限元软件及HyperMesh网格划分功能对楼盖结构复杂的斜向交汇预应力型钢混凝土梁-钢管混凝土柱节点进行数值分析,分析结果表明:该节点具有很好的承载力和刚度,各受力单元间具有良好的协同工作性能,同时为缩尺模型试验提供必要的数据支撑。采用1∶4缩尺模型试验,对节点在低周往复荷载下的力学性能进行研究,试验结果表明:该节点的滞回曲线饱满,具有良好的耗能能力,可实现"强节点强柱弱梁"的抗震设计要求。
Combined with a large passenger railway station elevated waiting hall floor structure,the finite element software ADINA and HyperMesh grid partition function are employed to analyze the complicated joint of the prestressed steelreinforced concrete beam and concrete filled steel tubular column based on numerical analysis. The results show that the joint has good bearing capacity,stiffness and cooperative work performance,which provide necessary data support for the following scale model test. The mechanical properties of the joint under low cycle reciprocating load are studied with 1 ∶ 4 scale model test. The test results show that the hysteretic curve of the joint is full with good energy dissipation capacity and can achieve the seismic design requirements of strong joint,strong column and weak beam.
