“…In another research work done by Issa et al [14] the investigation of the behavior coefficient of the concrete frame buildings of three, five and seven story with SeismoStruct software show that the value of the proposed behavior factor is less than the corresponding behavior factor in reported in Eurocode 8. The seismic behavior with nonlinear time history analyses of tall hybrid coupled wall systems is studied by Hung and Lu [15]. It is found that a tall coupled wall structure with uniform steel coupling beam sections over the structural height, ultimately leads to an average proportion of yielding coupling beams about 80%, which is consistent with beam designs methods with carefully tuned according to the vertical demand distribution gained by effective lateral load analaysis.…”

The behavior factor is used to reduce the elastic spectrum ordinate or the forces obtained from a linear analysis in order to take into account the non-linear structural properties. The more accurate this parameter is estimated, the more exact responses of the structures will be obtained. Recently, coupled walls with steel coupling beams are extensively utilized as an efficient system against lateral forces in high-rise buildings. But, there is not enough information about the behavior of these walls during earthquake, and design codes have not suggested any behavior factor for this structural system. Consequently, this paper is devoted to find the behavior factor of this structural system. To achieve this goal, six-, twelve-and twenty-story buildings are assessed. Except for the number of stories, all characteristics of these buildings are completely similar. Buidlings' height, the length of the coupling beams and the coupling ratio are key parameters which influence the behavior factor of the aforesaid structural system. In this work, the effect of these parameters on this factor are studied.
