摘　　要：对大悬挑结构和常规结构的各项整体性能指标进行了比较,并以实际工程为例,将这些指标分为关键控制指标和非关键指标两类,将层间位移角及其差异作为关键控制指标进行严格限制,将质量分布、周期、楼层刚度比、地震作用等作为非关键指标进行适当控制,使得大悬挑结构的设计具有更大的可操作性。In this paper,overall performance indicators of both large cantilever structures and normal structures are compared.Taking a project as an example,the indicators are divided into critical and non-critical control indicators.Critical control indicators such as story drift ratios and corresponding differences are controlled strictly.Non-critical indicators such as mass distribution,period,floor stiffness ratio and seismic action are controlled properly and therefore the design of large cantilever structures will be more operable.
