摘要
力密度法是张拉膜结构找形分析中最常用的方法之一 .文中论述了力密度法中T单元的应用 ,并探讨了网格离散方向及硬边T单元初应力取值对支撑构件的影响 。
Force density method is frequently used for form finding of tensioned membrane structure. In this paper the use of 'T element' in force density method is discussed, meanwhile, direction of cable net and the effect of prestress of fixed cable in 'T element' on braced structure are also studied. In addition, force density method is perfected in this paper.
