| dc.description.abstract | Most recent seismic codes include response modification factors (R in US practice) or behavior factors (q in European practice) in the definition of equivalent lateral force method of analysis used for the design of earthquake resistant buildings. Seismic design makes use of energy absorption and dissipation to reduce the design forces in order to achieve economy. The behavior factor (q) or response modification factors (R) plays a central role in seismic design process, since it is used to reduce the linear elastic design spectrum to account for the energy dissipation capacity of the structure. In this study the evaluation of behavior factor for regular and irregular ductile reinforced concrete structures using nonlinear analysis is investigated. The evaluation is done by designing regular and irregular structures for different ductility classes with the provision of our seismic code and by checking their performance through non-linear analysis using CSI ETABS. In this paper parametric studies have been conducted and the effects of different parameters (seismic location, ground type, number of stories, ductility class and 3D modelling effects) on behavior factor are presented in detail. Moreover, the evaluation of behavior factor using different models under favorable and unfavorable conditions along with performance comparison of structures designed for different ductility classes were done and the results are discussed and presented in this study. Furthermore, the evaluation of behavior factor for 3D plan irregular reinforced concrete structure under unfavorable conditions is done using non-linear dynamic analysis and the findings are presented as well. | en_US |
