Abstract Steel reinforced concrete (SRC) composite shear walls are typical structural components to resist the lateral loading in many high-rise and super high-rise buildings because of their excellent seismic behavior. In order to study the seismic performance of those structures, Open System for Earthquake Engineering Simulation (OpenSees) software was used to simulate the hysteretic behavior of the composite shear walls under low cyclic loading with nonlinear beam-column fiber element base on the other researchers’ experiments. The shear behavior of fiber sections was simulated by the nonlinear shear restoring force relationship in the section level. It is shown that the numerical results are in good agreement with the experimental results, and the fiber model considering the shear effect can predict the maximum shear force, pinch effect and stiffness degradation of SRC composite shear walls effectively. The proposed method in this paper can be refered to further elastic-plastic analysis on this type of structures.

Key words： steel reinforced concrete (SRC) composite shear wall fiber model hysteretic behavior OpenSees seismic behavior numerical model
