Abstract
The authors proposed a concept of RING TYPED-LATTICE MODEL to establish stress-strain relationships of plane concrete for finite element analysis in the previous researches. In the present paper, first, the formulation of constitutive equations based on the Lattice Model is detailed. Second, reinforced concrete panels subjected to biaxial stress conditions and cyclic pure shear loadings are analyzed and compared with experimental results. Furthermore, the constitutive equations are applied to finite element analysis of reinforced concrete shells to investigate the validity and applicability of the present formulation. The analyses are executed in the two structural cases of a cylindrical wall and a cooling tower subjected to cyclic horizontal loadings such as winds and earthquakes. These numerical results are compared with the experimental ones. Through comparison, it is proved that the constitutive equations are extensively available, however with some restrictions, to simulate the behaviors of reinforced concrete shells under cyclic loadings.
