This paper presented the result of analysis about R/C arch by use of finite element method. The design method for R/C shell has not been established due to its numerical difficulties. Using the finite element method, it was possible to analyze these structures. However, the precise experiments were required to verify the reliability of these analyses and it was necessary to improve the numerical analyses. An R/C arch is a basic form of the R/C shell. Under various conditions, that was, R/C arch without initial imperfection, different rise-span ratio, three types of loading points and supporting conditions, loading tests of R/C arch were performed. After experiment, analysis was also carried out. And as the result compared experimental and numerical results, accuracy of this analysis method was elucidated.
