Chamfering and reinforcement detailing in reinforced concrete corner subjected to opening moment

Abstract

Reinforcement detailing of reinforced concrete corner joints under opening moments has been a matter of research over the years. In the present study, an effort has been made to investigate the effect of chamfer as well as reinforcement detailing on the strength and behavior of opening corners. A linear finite element analysis supported by experimental program has been used for the investigation. A. simple strut-and-tie model (STM) for opening corner has been proposed to decide the area of reinforcement and its layout within the corner zone. Finally, the amount of reinforcement and chamfer to be provided in opening corners, including the case of liquid retaining structures, have been suggested.
