摘要
本文论述了力密度法找形分析原理并引入“T单元”的概念处理边界 ,建立了平衡方程组 ,完善了力密度法 。
Cables are important components in long span tensioned membrane structures. The concept of 'T element' is introduced in this study for the treatment of cable boundaries when applying the force density method in the form finding of membrane structures. This treatment improves the force density method and provides an effective method for the design of membrane structures.
