| Abstract: | In order to meet the needs of the practical structural design, the iterative formula and tactics for the form finding of cable roofs are proposed. It is called as the modified force-density method. The method is verified by some benchmark problems and big projects. Numerical examples show that the modified method is very simple and efficient. It can be used to find the shape of various pretensioned cable roofs. |
