摘　　要：梁柱装配式刚性节点是一种新型节点,它具有构造简单、整体性能高、安装方便等优点。分别采用等强度设计法、精确设计法和简化设计法对新型梁柱装配式刚性节点进行设计。在此基础上,考虑几何、材料和状态三重非线性,利用ABAQUS软件对节点进行了非线性有限元分析,得到了节点在单调荷载作用下的荷载-位移曲线及低周反复荷载作用下的滞回曲线,研究了按不同方法设计的节点的力学性能。研究结果表明:按照等强度法设计的节点具有较高的承载力,且在低周反复荷载作用下的滞回曲线较饱满,滞回环面积较大,表现出了良好的耗能性能。建议在设计此种形式节点时,优先考虑等强度设计法。The beam-column assembled rigid joint is a new type of joint which has advantages of simple structure, high integral property and convenient installation. Based on the equal strength design method, the accurate design method and simplified design method, the new type beam-column prefabricated rigid joint was designed. Then, the three-dimensional nonlinear finite element analysis was made by ABAQUS software considering the geometry, mate- rial and status triple nonlinearities. Moreover, the load-displacement curves under monotonic loading and the hysteretic curves under low cyclic loading are obtained. And the mechanical properties of joints designed by different methods were studied. The results show that joint designed by equal strength design method has more higher bearing capacity and its hysteretic curve is plumper. Therefore, it is suggested that the equal strength design method should be a prior selection when a form of this joint is designed.
