This paper presents a method of estimating resistances and deformations at cracking and yielding of high strength reinforced concrete columns. As for the cracking and yielding strengths, a good coorelation was obtained between test results and calculated from the flexural theory with the properties of high strength materials. Theoretical initial cracking deformations generally underestimated those observed in the tests. A stable cracking deformation was defined and calculated as an hysteretic characteristic point, which gave a fair estimation of the observed. Estimated yielding deformation was formulated as the sum of independent modes of deformations, such as flexural deformation from a flexural theory, shear deformation based on a truss and arch model and pull-out deformation in an empirical formula. The estimation method was varified through the experimental data.
