Abstract

Based on Iranian standard 2800, drift of each storey for the lateral seismic loading should not exceed
from mentioned values in this code. It is stipulated in the note of this article that in drift calculation, the
period of the building can be determined through experimental formula, mentioned in the code or be
calculated by the analytical methods. Regarding that experimental base formula normally give shorter
period, so they lead to stronger structures. Application of analytical base period for special moment
resisting structure leads to a structure with less weight and strength, which satisfy the criteria and thus is
acceptable. In this research, some buildings with special moment resisting slender structures considered
and designed twice based on two assumptions, with and without considering the article note. For this,
damage index of structures and endurance time of them, after nonlinear three dimensional time-history
analyses will be investigated. Analyses show that structure designed based on analytical period not only
has lighter structure, but also have better seismic behavior and more endurance time under “in” series
of ET records.
