In this study, the authors carried out an experiment and an analysis on early-age cracking of reinforced high-strength concrete as the rigid framed structure. Strains of concrete and reinforcement of column and beam were measured in an actual building under construction. The mechanical property parameters of concrete were also measured then used for the numerical analysis of thermal and autogenous shrinkage stress. Based on the results of these experiment and analysis, the authors made clear the formation of early-age cracking of these structural members.
