| Abstract: | 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. |
