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模型进行了合理的简化,以对原材料T型板、U型板进行的拉伸试验为基础,分析位移随荷载变化的曲线,得到了T型和u型两种截面型式板材腹板和底板的材料等效拉伸弹性模量,并与平板的拉伸弹性模量值进行了比较分析。A model of arch corrugated metal roof structure is simplified rationally based on the theory of orthotropic thin plate. On the basis of stretch experiments of T shape plate and U shape plate of raw materials, correlated curves of shift changed with load are analyzed. The elastic modulus of the equivalent stretching of materials of T and U shape of sectional web and back plates are obtained, of which is contrasted with that of a plane plate.
