    Abstract: Different types of dampers are used in buildings to reduce effect of earthquakes. This study tends
to evaluate seismic performance of IPFD which is a type of friction damper. For this purpose, two cross-braced
steel frames with and without dampers in different openings were modelled in SAP 2000 and exposed to
accelerograms of important earthquakes for non-linear time history analysis to examine effect of damper and
the number of openings on base shear, shear and displacement of stories.
