From the mechanics model of curving section shear strength on reinforced concrete slabs, this thesis analyzes the existing indefinable and solving method in projects. The reliability analysis of different models has been done. At the last, based on reliability theory,the practical expression of partial coefficient has been derived. The results provide scientific basis for defining the formulas of curving section shear-bearing capacity on non-stirrup reinforced concrete slabs. The method is applicable to other similar cases.
