Performance Based Evaluation of Reinforced Concrete Regular Structures

Abstract


The response reduction factor is crucial in the seismic analysis and design of new structures. IS 1893:2002,2016 provides certain response reduction factor values for typical buildings based on the kind of moment resistant frame building. This research aims at how to obtain the real value of the response reduction factor for regular frames with varied numbers of stories and to establish a comparative relationship for the response reduction factor between real and IS 1893 values. SAP2000 is used in an analytical method to examine the behavior of five distinct storeyed frames. The results reveal that the values proposed by the Indian code are on the safer side, however the response reduction factor varies as the number of stories changes.

 

Keywords: Performance-based design, Response reduction factor, Pushover analysis, Overstrength factor, Ductility reduction factor.
