A Quantitative Investigation on the Effects of Flexure-Dominated Reinforced Concrete Column Characteristics on the Dissipated Energy

Abstract

This paper presents the effects of fundamental member and loading parameters on total dissipated energy capacity of RC columns in quantitative way by using an experimental database. Specifically, concrete compressive strength, yield strength of reinforcing bars; shear span-to-depth ratio, reinforcement ratios; peak drift ratio, and axial load ratio, are considered as influencing factors. Pearson’s correlation coefficients are utilized as dependency indicators to construct a correlation matrix where the effect of each factor on dissipated energy level is quantified. Results show that the effective factors among selected features are peak drift ratio, transverse reinforcement volumetric ratios of a member, and yield strength of rebars whereas the most influencing factors are the first two.
