Abstract
Equations to estimate strength and deformation characteristics of confined concrete are investigated through discussions on our previous study. Main results obtained are as follows. (1) Equations to calculate strength and deformation characteristics of confined concrete are derived irrespective of strength of constituting materials and configurations of transverse reinforcement. (2)A method for predicting stress-strain relations of confined concrete using charts which express effects of factors on the strength and deformation characteristics is presented. (3) From examinations of feasibility, the induced equations show more successful applicability to test results than other privios equations.
