| Abstract: | Two kinds of form-finding methods based on nonlinear finite element, support-moving method and joint-equivalence method, are introduced and examined. By taking into account the advantages of the two methods and the characteristic of form-findings, a joint-directed moving method is presented. The numerical results show that the new method convergence more rapidly with more accurate precision, so it can be used practically. |
