Abstract
In recent studies on prediction of the behavior of reinforced concrete structures, it has been reported that compressive strength of cracked concrete is lower than that of uncracked concrete. But the overall behavior and the mechanics as to the strength reduction were not clear.
In order to examine the strength reduction, the authors conducted the experimental research using hollow-cylinder type of reinforced concrete specimens.
The result shows that strength reduction can be expressed by the function of crack width and crack spacing. But within the experimental range, however, avarage tensile strain normal to crack uniquely decides the nonlinear behavior of cracked concrete.
