| Abstract: | The model of the arched corrugated metal roof structure is simplified on the basis of the theory of orthotropic thin plate, based on the stretch experiments and the bending experiments of ladder-type section and U-type section of raw materials thin plate, corelation curve about loads and deformation is analyzed, the material equivalent rigidity curve of sternum and backplate of two type section had been derived and compared it with rigidity curve of plate. |
