The authors have proposed the ring type-latticed model to establish stress-strain relationship of concrete for finite elements in the previous report. In the present paper, firstly, the formulation of constitutive equation based on the latticed model is elaborated. After that, the behaviors of the latticed model are investigated by comparing them with the experimental results of reinforced concrete panels under cyclic pure shear loadings. Furthermore, the constitutive equation is applied to finite element analysis of reinforced concrete shells. The analyses are executed for cylindrical and boxed walls under reversible cyclic horizontal loadings. And the analytical results are compared with experimental ones. Through the comparisons, it is confirmed that the constitutive equation is available to simulate the behaviors of reinforced concrete shells under reversible cyclic loadings. Simulations under various reinforcement and shear-span ratios are also performed by using the proposed model.
