摘　　要：建立了加强后的金属拱型波纹屋盖模型,利用ANSYS有限元分析软件对加强后的波纹拱进行了荷载作用下几何非线性有限元分析,并与原波纹拱进行了变形与应力的比较。计算结果表明,加强后的波纹拱对约束结构位移变形有较好的效果,且提高了结构的承载能力,这一结论为该结构进行抗风、抗雪等设计提供了有益参考。The models of strengthened MACR are put forward, and by making use of the program of ANSYS finite element analysis, the geometric non-linear finite element analysis of strengthened MACR is carried out under load. The displacement and stress of this new structure is compared with the old structure. The finite element analysis proves that the plan has good effect on decreasing the displacement, and it has good effect on improving the vertical load-bearing capacity of the structure. Some references for the design of anti-wind, anti-snow of the structure are provided by the study achievements in this paper.
