| Abstract: | In the paper,the mechanical properties of cable dome was studied according to nonlinear finite element theory,a model of geoponic depository which attributes to cable dome structure was constituted by using the ANSYS software,the mechanical conditions of the structure under different prestress was discussed ,and the inner force variation conditions under different force and its influence on the stability of the structure were analyzed. The results prove that the mechanics properties of the model is reasonable and it can be used in project. |
