［摘要］上都阁楼属于塔类阁楼式建筑，其建筑体型从下至上呈逐层收拢的趋势，使外檐柱从下至上竖向不连续。结构设计时结合建筑造型及布置特点，采用了“绑扎式”搭接柱连接方式进行了竖向构件的转换，给出了“绑扎式”搭接柱的计算简化模型，分析了“绑扎式”搭接柱对结构抗震性能的影响及其受力机理，并提出了“绑扎式”搭接柱的结构构造加强措施及设计建议。

Abstract:Shangdu Pagoda belongs to Attic-style pagoda, and its architectural size becomes smaller and smaller gradually from bottom to top to make the outer structural columns vertically discontinuous from bottom to top. Combining with the architectural style and layout features in structural design, the binding lapping column connection was used to convert in the vertical members. The simplified calculation model of binding lapping column was provided, and the mechanical behavior of binding lapping column was analyzed as well as impact of the column on the seismic performance. Structural construction strengthening measures and design suggestions were put forward for the binding lapping column.

Keywords:Attic-style architecture; binding lapping column; seismic performance; structural construction
