摘　　要：开发地铁上部空间是提高城市土地利用率的一个有效途径。在工程实践中,这类建筑通常会用到带转换层的框架结构,该种结构存在竖向体型收进或设置多塔、塔楼偏置、转换层等设计难点。采用动力弹塑性时程分析方法,通过分析某地铁车辆段上盖带转换层框架结构在不同强度地震动输入下的非线性动力响应、转换层关键构件内力分布,研究了这种结构的抗震性能,并对类似结构提出了设计建议。Development of the upper space above the subway is an effective means to improve the utilization efficiency of the urban land. In many practical engineering examples, the frame structure with transfer storey is widely used. There are some difficulties in design of this structure, including vertical facade setback or multiple towers, the bias tower and the transfer storey. The seismic performance of this kind structure was studied with dynamic elastic-plastic time-history analysis method by analyzing the nonlinear dynamic responses under different ground motion inputs and the internal force distribution of key components of the transfer storey, which provides some suggestions on the design of similar structures.
