| Abstract: | The changes of structure in construction must be considered for the long-span steel roof's force difference between construction process and after forming.According to the construction characteristics,the overall program of unloading process is introduced.Through simulation analysis of unloading process by using ANSYS,the variation range of stress and deformation is confirmed,and field data are compared,accumulated experience and data will be available for similar structure unloading. |
