Statistical Evaluation of Response Modification Factors for Reinforced Concrete Structures
The report presents a statistical evaluation of the response modification factor for reinforced concrete structures. The response modification factor R is defined as the ratio of the absolute maximum linear elastic base shear to the absolute maximum nonlinear base shear of a structure subject to the same earthquake accelerogram. Twelve structural models with various dynamic characteristics are first constructed. Next, 90 synthetic earthquakes are generated from three power spectra representing different soil conditions. The nonlinear and corresponding linear time history analyses are performed to produce structural response data. On the basis of these data, an empirical formula for the response modification factor is established from a multivariate nonlinear regression analysis.
