Computer-aided analysis of reinforced concrete columns subjected to axial compression and bending. Part II: T-shaped sections

Abstract

This paper presents the writer's experience in investigating numerically the strength behaviour of short T-shaped reinforced concrete (RC) columns in order to provide design aids for structural engineers. Computer programs were developed for the analytical study of T-shaped RC column sections subjected to uniaxial/biaxial bending with axial compression. The interaction curves for L-shaped members, in Part I [Mallikarjuna and P. Mahadevappa, Comput. Struct. 44, 1121-1138 (1992)], and for T-shaped sections, in the present paper, were derived to provide advice for design information. This paper deals with the definitions and materials that are used in the limit state design of reinforced concrete structures. The programs presented here are written to operate in a conversational mode so that the analyst can respond to messages from the computer. 1994.
