This paper presents an analysis method more universal and accurate for reinforced concrete(RC) crossed beam on elastic foundation by means of finite element method(FEM).Analysis problem of non-orthogonal foundation beam of reinforced concrete is resolved.A corresponding computer program has been carried out.The correctness of the method has been proved by comparing actual example computed by our method with computing results in lieratures.
