Bearing concrete wall (BCW) system is one of the appropriate structural systems for average height buildings that based on the number of walls in plan and reduction in lateral force contribution, this system in addition to its strength against earthquake, according to volume of construction materials is economic. Therefore, vulnerability analysis and retrofitting of this structural system are of particular importance. To evaluate of BCW systems, a vast study on several models with different stories and several nonlinear analysis are performed. After 3D modeling in Perform-3D software, nonlinear dynamic analysis for two record sets of near and far field is done. To ensure the accuracy of modeling by fiber section method, the analysis results have been validated by the results of experimental models of precast concrete shear walls. Vulnerability assessment are done for risk levels of 475 and 2475 years and performance levels of IO, LS and CP and need of retrofitting with desirable rehabilitation aim is studied. The results indicated that, the models are provided desirable rehabilitation aim of seismic rehabilitation guideline.
