Evaluation of Response Modification Factors for RCC Frame Structure

Abstract

This paper presents research carried out on beam column connections of Reinforced Concrete Structures to
evaluate Response Modification Factors. R factors are important seismic design tools, which characterizes the level of
inelasticity expected in structural framework thought an earthquake incident. R factor reflects the capacity of structure to
dissipate energy through inelastic behavior. R factor is utilized to decrease the design forces in earthquake resistant
design, accounts for energy dissipation capacity, damping and for over-strength of the structure. RCC beam column
connections were subjected to quasi-static testing procedures and the data collected using data acquisition system was
analyzed to compute structural parameters including R-factor. It has been concluded that Scatter value of R exists as
compared to a single value of R= 8.5 being adopted in BCP SP-07.
