MODELING TENSION IN REINFORCED-CONCRETE MEMBERS SUBJECTED TO BENDING AND AXIAL LOAD

A constitutive model for tension in cracked reinforced concrete member s is presented. Special emphasis is placed on the bond between concret e and reinforcement as the main factor influencing tension stiffening in cracked reinforced concrete. The model was developed for members su bjected to bending and axial loads. The constitutive formulation was i mplemented into a cross-sectional analysis program and was used to ana lyze 14 specimens, which were tested in bending and in-plane loading. The comparison between the experiments and the analyses is presented a nd shows the same special characteristics for both the experimental re sults and the analyses.
