Steel plate shear walls have been used more frequently in recent years as the lateral load resisting system in the design and retrofit of high-rise buildings. Expected low cost fabrication, speedy erection, and good energy absorbing potential make the steel plate shear wall system an attractive alternative for the seismic upgrading of existing buildings. A new structural steel lateral load building system, called the steel plate shear wall (SPSW) currently under development in Canada, United States, Japan and other countries is gaining interest for its potential application in the seismic upgrading of buildings. While SPSW system can be easily integrated into existing steel frames, its suitability in concrete frames is still in the development stage. This paper concentrates on analytical studies of steel plate shear walls added to concrete frames. First using the fiber-based finite element analysis we propose an analytical model and verify this model by several experimental results (Numerical modeling has been developed in SeismoStruct). This model has been used to compare the behavior of concrete frames with and without steel shear wall. Then we continue our investigations with a parametric study on the behavior of concrete frames retrofitted by steel plate shear wall. We study the influence of changing in parameters such as concrete and steel plate characteristics, width to height ratio of frame and etc on behavior of such frames. Based on analytical results, some design recommendations for the structural system have been proposed
