摘　　要：运用有限元数值分析软件ABAQUS建立半刚性端板节点模型,对其在循环荷载作用下进行非线性有限元分析,并与相应的试验结果进行了比较验证。结果表明:用ABAQUS建立的有限元模型能够准确地模拟端板节点在循环荷载作用下的整体受力性能,为进一步运用该模型对各种不同形式和构造的端板节点进行全面的有限元非线性参数分析计算提供了正确依据。并分析得出了端板厚度、螺栓直径、螺栓布置、端板加劲肋等因素对端板节点承载力、极限转动能力、耗能能力和延性的影响特性,为半刚性端板节点的抗震设计提供了参考依据。The nonlinear finite element analysis of end-plate connection models under cyclic loadings were taken in the finite element software ABAQUS,and with the corresponding test results were compared. The result indicated： the software ABAQUS can accurately simulate the overall mechanical properties of end-plate connections under cyclic loadings. And this provided a correct basis for further nonlinear parametric analysis computation to different forms and structures of end-plate connections. The influence properties of different end-plate thickness, bolt diameter, layout of bolts and end-plate stiffener on joint bearing capacity, rotational stiffness, energy dissipation and ductility were analyzed, providing a reference for the seismic design for semi-rigid end-plate connections.
