This adverse effect can be mitigated by adding zipper columns or vertical members connecting the intersection points of the braces above the first floor. This paper critically evaluates over strength, ductility and response modification factors of these structures3, 5 and 7 story structures were modeled and analyzed. Static pushover analysis, linear dynamic analysis and nonlinear incremental dynamic analysis are performed by OpenSees software concerning 15 records of past earthquakes. &nbsp;In this paper, Analysis of different performance levels by comparing fragility curves and behavioral parameters in zipper bracing structures under increasing dynamic analysis. Seismic analysis of 3rd, 5th and 7th floor structures was performed with Zipper bracing structural system. Fragility curves were obtained for functional levels IO, LS and CP. The fragility curves have been plotted for the zipper bracings for the first time. These curves can be used as the bases for estimating seismic demands and performance based design of the structures for such bracings. As a general conclusion, the results showed that the RLRFD parameter increases with increasing altitude. The RASD parameter also increases with increasing altitude. As the height increases, the parameter Rμ increases. But for the parameters Rso and Rs the results showed that the maximum value is obtained in a 5-story structure. As the height and floors of the structure increase and decrease, it decreases to 5 and 7 floors of two parameters Rso and Rs</p>}, number={2}, journal={International Journal of Modern Agriculture}, author={Mehdi Khoshvatan, Mehrdad Movahednia, Rohollah Mohammadi}, year={2021}, month={May}, pages={2740 - 2755} }
