Abstract
Seismic analysis is considered as an important parameter for any structural design. The strength and ductility of frame members in seismic design depends on the response reduction factor. In my project 3 framed structures are considered of different heights under the Fourth zone condition. The primary emphases of this work are regarding calculation of response reduction factor values attained from designing RC framed structures. The results are computed by applying non-linear analysis. ETABS software is used for analyzing the non-linear behavior of the structure. Hence, in the present research, it is attempted to investigate the sufficiency of the code-based ‘R’ factor in assessment of seismic behavior using nonlinear dynamic analysis (NLD) for the structural models considered. Moreover, the results obtained, clearly envisages the influence of structural configuration changes on dynamic characteristics in terms of ductility and over strength values. It can be clearly observed that, the code specified constant ‘R’ for a particular structural type appears erroneous, emphasizing the need for its adequate estimation. This should involve consideration of the dynamic characteristics of the structure resulting in a realistic assessment of seismic demand, thereby contributing to a safe, functional and economical design configuration.
