Abstract

To evaluate visible damage of reinforced concrete (R/C) members such as crack width and length, cyclic load tests of one third scaled R/C members are carried out. Based on the tests, a damage estimation model is proposed to quantify each crack width and corresponding length. The model consists of a geometrical relationship between the sum of crack widths and drift ratio and a probabilistic model between crack widths and lengths. The proposed model shows that estimated flexure crack widths successfully approximate the measured crack widths in Specimen F-1 designed to fail in flexure. But in Specimen S-1 designed to fail in shear, estimated shear crack widths overestimate the measured crack widths at peak load stages and underestimate them at zero-residual drift stages. And the probabilistic model between crack widths and lengths are discussed.
