response of coupled-precast shear walls subjected to cyclic loads

large panel precast structures are analyzed based on the connection rigidity. however, the connections undergo nonlinear and inelastic response, when subjected to seismic loads. thus, to study the actual behavior of structure, the connection nonlinearity should be implemented in the joints. in this paper, three conventional connection types are modeled based on the envelope of their cyclic responses using ansys program. the results reveal that the behaviors of modeled connections are very close to experimental results. the nonlinearity of connection is modeled in the coupled-precast shear walls, as a lateral load resisting elements, and several analyses are preformed. the results show, when the nonlinear behavior of connection are considered the forces in the connections are smaller up to 6.7 times and the displacements are greater up to 4 times in comparison with those for rigid connection state, respectively
