| Abstract: | Starting from the basic principles of force-density method,according to the theory of the finite element,some improvements are made for the force-density method,put forward a new concept of force-density matrix of element,and combined the CSR storage method and GAUSS_SEIDEL iterative method to solve the problem of form-finding of membrane structure.Using Fortran95 computer language,the corresponding computational programs are accomplished and the computation of practical example is done.Compared with the tr... |
