Abstract :

Abstract In previous earthquakes, the effect of infill in the structures has shown the importance of modeling and evaluating their influences in analyzing and designing the structures. Different modeling methods have been presented up to now in this field. In this research, the effect of infill with various number of stories is investigated by pushover method. The results of this research reveal that the expected behavior of the structures with and without infill differs significantly. Also with increasing the number of stories, values of initial stiffness, periods, shear values and drift in buildings with infill vary basically in comparison with building without infill.
