摘要
本文对板采用四结点分层板弯曲单元,对柱采用八结点六面体等参单元,建立了钢筋混凝土板柱节点有限元非线性计算模型,编制了反复荷载下钢筋混凝土非线性有限元计算程序。文中介绍了作者进行的板柱节点在反复荷载作用下的试验结果,用试验数据验证了所建立的有限元程序的可靠性。文中对板柱中节点和边节点在竖向剪力和低周反复水平荷载共同作用下的受力性能进行了全过程计算分析。
By the use of four-node layered finite elements for slab and three-dimensional isoparametric finite elements for column a nonlinear reinforced concrete finite element analysis model is established. The behaviors of the reinforced concrete slab-column connections under the combined action of vertical load and lateral reversed load are studied. The computational results by finite element analysis agree well with the experimental ones.
