摘　　要：设计并实施了 16组金属拱型波纹屋盖结构足尺模型试验。通过这些破坏性试验 ,对这种结构在全跨及半跨荷载作用下的力学性能有了一个直观认识。试验得出的结论不仅可作为建立结构分析理论的依据 。The full size test on the arched corrugated metal roof is carried out in the paper Sixteen groups of models span 7m to 37 8m with the width from 1 5m to 3 66m A scaffold is installed around the model The lateral stability of the model is guaranteed Throrgh the destructive test,the load?resistant curves of full?span and half?span loading are acquired It is found that the deformation of the model is somewhat large for its smaller stiffness The nonlinear behavior of the model is appeared Some useful conclusions are obtained through the study
