Finite Element Behaviour of RC Beam with Hybrid Arch Profile

7 pagesPublished: July 22, 2017

Abstract

A detailed study has been conducted for understanding the structural behaviour of a beam with Hybrid profile consisting of a concrete arch tied with steel reinforcement. The compression region generated due to flexural loading is converted into an arch which is connected by providing reinforcement at the bottom. The structural performance of this type of beam is not known yet owing to its complex shape and novelty. The main goal of the study is to examine the static behaviour of this beam under flexure and different support conditions comprising of simple support with and without horizontal restraint. Finite element analysis for the developed beam is conducted using standard FEA package. The results indicate that the strain at the level of steel in arch beam reduces by 31.8% with horizontal restraint whereas without horizontal restraint, there is an increase of strain by 50% as compared to beam having rectangular section with similar loading condition and flexural rigidity. The self-weight of the developed beam was reduced by 45% compared to conventional rectangular section. This study shows that the performance of the developed beam improves significantly if a suitable support conditions are provided.
