摘要
金属拱型波纹屋面向形状复杂的波纹构成，结构分析非常困难。为此把带有波纹的底板和腹板分别等效为正交各向异性平曲板，并通过拉伸和剪切试验得到了其两个方向的等效材料常数。算例表明了这一简化计算模型的可靠性。
Metal corrugated arch roof is composed of irregular corrugations.The structural analysis is very difficult. The web and flange plates with a large number of corrugations are equivalent to orthotropic curve plates and their equivalent material coefficients are obtained by stretching and shearing experiments. An example shows that this simplified calculating model is reliable.
