【 摘 要 】

The RC shear wall under monotonie loading was analyzed with a two -dimensional model of flexibility method based on fiber, considering the axial, bending and shear effects. The calculation program to simulate a shear wall's nonlinear performance under monotonie load was programmed. The model is validated by comparing calculated values with experimental data on laboratory RC shear wall. After verifying the feasibility and the validity of the model, the factors affecting the nonlinear performance of shear wall are analyzed, such as aspect ratio, axial compression ratio, reinforcement ratio, concrete strength.
