Evaluation of Ductility of Bearing Concrete Wall Systems with Regard to their Boundary Element

Bearing Concrete Wall (BCW) is one of the most applicable structural systems. In this paper, with the aim of evaluating bearing wall performance, nonlinear static analysis based on several assumptions drawing upon experimental research is used. To validate the nonlinear analysis method, the analytical and experimental results are compared. To evaluate the reduction factor and ductility level of BCW systems, a vast study on several models with different stories and several nonlinear analysis are performed. The results indicated that, the components of the boundary element have a limit effect on the models’ ductility factor. Also, the reduction factors show acceptable values for building height up to 50 meters and the decreasing rate of this coefficient is increased in the higher elevations.
