Use of angle steel as internal reinforcement in low strength concrete: an experimental study

Abstract

Use of angle steel as reinforcement in concrete is a prominent field of research nowadays. This paper presents an experimental study where angle steel is used as reinforcement in concrete members like column, beam, and frame. The effects were compared with the members prepared with the conventional round bar as reinforcement. It is found that structural RCC concrete members having angle steel performed better than the structural concrete members having conventional reinforcement. The study revealed that the load-carrying capacity of the column, beam, and frame reinforced with angle steel were 5.4%, 28.16%, and 42.29% higher than those of the column, beam, and frame respectively, reinforced with conventional steel even though the yield strength of angle steel was less than the conventional rebar and also the steel usage was found 13.73% less for angle steel.
