Abstract: 
One of the common structural systems in designing tall buildings is wall-frame system, which is highly efficient for buildings not taller than 50 stories. By considering wall and frame static interaction in wall-frame system, cutting the shear wall in an optimum level (based on the least displacement of the top) makes possible extinguishing extra forces in frame members. In this study the behavior of wall-frame structures under the lateral forces due to earthquake was investigated and through studying the optimum point of shear wall curtailment, by considering the dynamic wall and frame interaction. The optimum point of the shear wall curtailment is studied in order to extinguish extra forces in frame members and minimize the top of the structure deflection. This study was done by modeling and analyzing structural models and using equivalent static load of the Iranian 2800 earthquake code, response spectrum of the 2800 code, time histories of Tabas, Naghan , Manjil and El Centro earthquakes.
