Based on the idea of fiber model, a fiber wall element model was put forward, which was com posed of fiber element that represents the flexural deformation only, and shear element that represents the shearing only. In this model, the height of shearing element and stiffness matrix of the proposed ele ment, and its skeleton and hysteretic curves were also built up. Using the fiber wall element, the dynamic responses of a 40story shear wall structure were computed and compared to the shaking table test of the same model structure. The good agreement between them indicates that the fiber wall element model pro posed here is reasonable and efficient in the nonlinear analysis of shear wall structures.
