| Abstract: | The large-scale steel structure roof is a surface steel structure system composed of spatial pipe truss. Using the finite element method simulation,the pre and post deformation of the roof was analyzed during the unloading.According to the deformation,the unloading thought of the roof was made. Also, the stress and strain of the typical parts were studied, which provided the calculation for the safety of the whole structure unloading. |
