摘　　要：钢梁节点的抗震性能是确保钢结构安全性的重要因素,结合实际建筑的加固需求,分析该建筑加固节点的抗震性能。结合工程加固需求,设计J1和J2两种尺寸的加固节点,通过ABAQUS有限元软件构建节点有限元模型,模拟不同加载级作用下的节点受力和变形情况,以评估其抗震性能。同时,结合试验数据对模拟结果进行验证和分析,确保研究结果的准确性和可靠性。分析结果表明:在相同位移加载级下,节点构件J1抗震性能优于J2,其刚度退化较慢,没有发生显著的局部集中式应力分布,抗震性能更佳。The seismic performance of steel beam joints is an important factor to ensure the safety of steel structures.In this paper,the seismic performance of the steel beam joints is analyzed according to the reinforcement requirements of actual buildings.According to the requirements of engineering reinforcement,J1 and J2 reinforced joints were designed,and the finite element model of the joints was constructed by ABAQUS finite element software to simulate the stress and deformation of the joints under different loading stages,so as to evaluate their seismic performance.At the same time,the simulation results are verified and analyzed with the test data to ensure the accuracy and reliability of the research results.The analysis results show that the seismic performance of joint member J1 is better than that of J2 under the same displacement loading stage,and its stiffness degradation is slower.There is no significant local centralized stress distribution in the stress cloud map,so the seismic performance is better.
