Abstract
The objective of this paper is to study the size effect in eccentrically loaded stocky reinforced concrete (RC) columns from both experimental and numerical perspectives. An experimental campaign was carried out on eccentrically loaded RC columns of full-scale to facilitate a more accurate understanding of the influence of eccentricity on the failure behavior and size effect. A total of 30 geometrically similar RC columns sized from to was tested with the eccentricities of , , , , and ( denotes the effective cross-sectional height). A brittle-ductile transition behavior according to the initial eccentricity was found from the test observations, and a comparison of the present test results and the SEL proposed by Bažant was made. Meanwhile, a mesoscale numerical method for the simulation of failure behavior of RC columns was proposed. Good agreement between the present simulation results and the test observations of the RC columns without transversal reinforcement illustrates the reliability and accuracy of the numerical approach. The verified mesoscale approach was then extended to study the failure behavior of RC columns having transversal reinforcement, and the confinement effect was also discussed.
