Abstract – This paper deals with effect of friction dampers on seismic response of
2D steel frames in comparison with structures stiffened by large sections and centrally
braced. For the present study three structures with six storeys are subjected to a time
history analysis. To study the effect of dampers in structures in comparison with
structures stiffened by large sections and centrally braced, are analysed the relative
level displacements, maximum displacement on the top, variation of lateral
acceleration at the last level and variation of the maximum seismic base shear force
depending on the lateral rigidity. The results indicate that placement of friction
dampers improve the response of structures in all analyzed terms.
