In this paper,after taking the effect of axis force on bending into consideration,the general poteneial energy for the circlular double articulated arch is established undergoing vertical distributive load g0/cos2θ.With sufficient engineering precision,the fourth approximations to the destablizing critical load of the arch under this load are obtained by Ritz method.The approximations to the critical load table are listed for various center angles of arch,and are contrasted with the critical load circular arch undergoing radial uniform load.Some reference results have been obtained.
