Determining structural maximum deformation under earthquake excitation is an important problem in seismic design of structures. There are several approaches in order to estimate an acceptable accurate response for maximum drift of the structure in nonlinear region. Both ATC and FEMA approaches are good ideas to evaluate maximum drift but more simplified approaches should be applied in seismic design codes. Most of seismic design codes suggest a very simple relation for estimating maximum drift in design base earthquake. Iranian seismic code of practice (Standard No. 2800) proposes such a relation. In this paper a comparison between nonlinear dynamic results and code suggested relation is carried out. 3 scaled records have been used for analysis. Based on reduction factor calculated for the structure, a comparison has been carried out with the suggested factor in Iranian Code of Practice (Standard No. 2800).
