T-SHAPED REINFORCED CONCRETE MEMBERS UNDER BIAXIAL BENDING AND AXIAL COMPRESSION

The paper presents an experimental and analytical study of T-shaped reinforced concrete members under biaxial bending and axial compression. The strength and deformational behavior of T-shaped reinforced concrete members under biaxial loads monotonically up to failure are explored. The theoretical predictions agree well with the experimental data of 12 test specimens reported herein. Of the total 12 test specimens, nine were made with normal weight concrete, one with fly ash concrete, and two with high-strength concrete. The strength interaction curves and load contours of T-shaped members are derived in this paper to provide advice for design information.
