ABSTRACT In this paper, the effects of form parameters on the structural efficiency of tall buildings are investigated by generating a parametric platform. The modifications of the form are normally adopted by architects in tall buildings to satisfy their aesthetic and functional needs. The effects of tapering and changing plan shape as two commonly used modifications, are investigated applying the diagrid structural system which provides the structure with high stiffness and efficiency as well as satisfying the architectural needs. Forms are generated in Rhinoceros and exported to SAP2000 to be analysed structurally through a response spectrum analysis. The results show tapering in the height section leads to more impacts on structural efficiency parameters in comparison to plan changes. The circle and the polygons with more sides create more efficient forms. Some outcomes show more than 20% lighter structures in concave sections than normal buildings.

斜肋高层建筑的结构效率参数化设计

摘要在本文中，通过生成参数化平台研究了形状参数对高层建筑结构效率的影响。高层建筑中的建筑师通常会采用对形式的修改，以满足他们的审美和功能需求。锥形和改变平面形状作为两种常用修改的影响，应用斜肋结构系统进行了研究，该系统为结构提供了高刚度和效率，同时满足了建筑需求。表格在 Rhinoceros 中生成并导出到 SAP2000 以通过响应谱分析进行结构分析。结果表明，与计划变更相比，高度部分的锥形对结构效率参数的影响更大。圆形和具有更多边的多边形创建更有效的形式。一些结果表明，凹形部分的结构比普通建筑物轻 20% 以上。
