摘　　要：按照正交各向异性薄板理论对金属拱型波纹屋顶结构进行了合理的简化。以对原材料T形板、U形板进行的弯曲试验为基础，分析位移随荷载变化的曲线，得到了T形和U形两种截面型式板材腹板和底板的材料等效弯曲弹性模量，并与平板的弯曲弹性模量值进行了比较分析．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.
