| 摘 要： | 通过纤维模型模拟构件的轴力和弯矩作用,添加单轴剪切弹簧考虑构件的剪切性能,对钢筋混凝土核心筒进行了数值模拟计算分析,研究了核心筒在不同轴压比、连梁刚度、配筋率、高宽比以及加载角度下的力学性能,并与试验进行对比,结果吻合较好,表明纤维模型对核心筒分析的有效性。

| Abstract: | Axial compression and bending behavior of reinforced concrete core walls can be simulated base on the fiber model.the unaxial shearing spring is introduced for considering the shearing behavior of core walls.Based on the existing experimental data and the fiber model,finite element model of core walls are established reasonably.Then the influence of axial compression ratio,reinforcement ratio,load action direction,ratio of height to width and stiffness of coupling beams on the capacity and deformation of co... |
