| 摘 要： | 钢筋混凝土结构物中次梁与主梁的连接方式分为铰结点和刚结点,在结构计算中简化为何种连接方式应视主、次梁的尺度和配筋情况等而定。以数值模型计算分析为基础,探讨在不同荷载作用下主、次梁节点的不同连接方式对主梁应力和变形的影响,以及主、次梁节点的协调扭转、协调扭转的零刚度等关键技术问题,可供同类型结构设计参考。

| Abstract: | Rigid joint or hinged joint may be applied to connect the girder and beam in reinforced concrete structure, but final connecting way should be determined by the dimensions of girder and beam as well as the detail of reinforcing bars in structural calculation. Based on numerical model calculation and analysis, we discuss the influence on girder stress and deformation by the joint connecting ways of girder and beam under different loads, the coordination and torsion for the joints of girder and beam, zero rigidity of coordination ＆ torsion and other key technical issues, which will provide the reference for similar structure design. |
