摘　　要：悬挑结构经常由于能够实现较好的外立面视觉效果而被广泛应用,同时对结构设计过程带来了尺寸突变这一不规则超限项,应采取对应的加强措施。本研究介绍了某悬挑超限高层的结构设计,从结构体系、超限项判别、抗震性能目标等多维度进行描述。计算结果表明,结构具有良好的抗震性能,可满足规范要求的抗震性能化目标。Cantilever structure is widely used due to their ability to achieve better visual effect on the exterior facade,at the same time,brings irregular size changes in the structural design process,which should be strengthened accordingly.This article introduces the structural design of a cantilever over-limit high-rise building,elaborating on the structural system,over-limit discrimination,seismic performance goals.And the calculation results indicate that the structure has good seismic performance and can meet the seismic performance goals required by the specifications.

关 键 词：超限高层 悬挑 性能化设计
