To study the seismic performance of exterior joints in tall-building structure,7 exterior beam-column joints with high-strength concrete were analyzed by software ABAQUS.And hysteretic curves and skeleton curves of exterior joints were obtained.The analytical results of skeleton curves were compared with experimental results.Thereafter,the influence of parameters on seismic performance of this kind of joints were investigated,which included axial compression ratio,concrete strength grade in exterior joints core region and extending length of column′s concrete into beams.The results show that the rules for the bearing capacity and deformation of the joints with various parameters match well with the experimental results.%为了研究高层建筑结构边节点的抗震性能,采用有限元软件ABAQUS对7个高强混凝土梁柱边节点进行了分析,得到了各构件的滞回曲线和骨架曲线,并将骨架曲线与试验结果进行了对比分析.在此基础上,研究了高强混凝土梁柱边节点在不同轴压比、节点核心区的混凝土强度等级和柱中混凝土在梁中的延伸长度等影响因素下的抗震性能.结果表明,节点承载能力和变形性能随各影响因素变化的规律与试验结果吻合较好.
