Abstract: | Based on the force-density method,this paper deduces the formulations of mixed force-density method,solving the form-finding problem of the tensile membrane structure with elastic piles. The corresponding computational program is accomplished and the computation of practical instance is done. The result proves that the mixed force-density method has good stability,convergence and precision,and fits for the mixed form-finding of tensile membrane structure. |
