In this study, a method for calculating the ultimate shear strength of reinforced concrete (RC) beams using various light-weight aggregates was suggested oh the basis of the design guidelines for earthquake resistant concrete buildings based on ultimate strength concept. In this methodology, the brittle degree coefficient of light-weight concrete was regarded as the important material characteristics in high correlation with compressive strength of concrete partitioned into strips by cracking, and the brittle degree coefficient was mutually related with the effective factor, v of compressive strength in the arch mechanism, which was derived by means of the inverse analysis from the present experimental results on the ultimate shear strength of RC beams without shear reinforcement. As a result, it was shown that this method gives reasonable agreement with the experiments on the ultimate shear strength of RC beams using various light-weight concretes.
