摘要:
运用有限元软件OpenSees建立了框架结构梁柱节点数值分析模型,对2个梁柱节点试件在低周反复荷载作用下的抗震性能进行了数值模拟,模拟结果与试验结果比较吻合,表明所选择的材料本构关系及相关材料参数取值,对于模拟钢筋混凝土框架结构的抗震性能具有较好的适用性和合理性.利用所建立的模型,分析了在框架结构梁柱节点一定尺寸范围内使用纤维增强混凝土(FRC)FRC的新型框架结构梁柱节点具有较高的承载能力和耗能能力;随着FRC使用范围的增大,相应梁柱节点的承载能力和耗能能力提高不大.
Abstract:
he numerical analysis model of the beam-column joints using the finite element software OpenSees was built and numerical simulation of the seismic behavior of two beam-column joints specimens under low reversed cyclic loading were carried out. The simulation results coincide with those of the experimental results, showing that the choice of the material constitutive relation model and related material parameters for simulation the seismic behavior of reinforced concrete frame structure have good applicability and rationality. By using this model, the seismic behavior of the new frame structure, whose beam-column joints within a certain size using fiber reinforced concrete (FRC) were analyzed. The results showed that the beam-column joints with fiber reinforced concrete in partial section have higher bearing capacity and energy dissipation ability. With the increase of the region of FRC, the corresponding bearing capacity and energy dissipation ability do not increase much
