摘　　要：通过拟静力试验以及有限元ALGOR程序,对翼缘削弱型刚性连接节点进行了低周反复荷载作用下试验研究和非线性有限元分析,研究了翼缘削弱型刚性连接节点的破坏形式和受力性能.分析结果表明:翼缘削弱型刚性连接具有较大的连接刚度和理想的耗能性能;梁翼缘处的焊缝强度是决定翼缘削弱型刚性连接节点性能的主要因素,这为翼缘削弱型节点的研究和应用提供了理论依据.By quasi-static test and finite element ALGOR program, the experimental research and non-linear finite element analysis are made under low-cycle repeating horizontal load. The damage form and mechanical performance are studied. The results Of analysis indicate that the flange weakening type rigid connection has bigger connection rigid and better behavior of absorbing earthquake energy. The welding sew stress of beam-flange is the major factor which decides the behavior of flange weakening type rigid joint, and the connection between web of beam and flange of column has less impact on strength of connection joint under the condition of reasonable design. These results provide theoretical basis of study and application of flange weakening type connection joint.
