Parametric analysis and finite element modelling for shear behavior of positive haunched RC beams

Abstract

This article aims to explain the actions of reinforced concrete beams (RCHBs). (RCHBs). Based on the analysis of previous books, it could be observed that the pieces of study on the actions of haunches beams are quite unusual and to the awareness of the scholar, the latest studies have not dealt with this subject in greater detail. This article aims to explore the structural reaction and strength capability of RCHBs exposure to two-point load for shear behavior by conducting nonlinear static analysis by ABAQUS. For estimating the nonlinear behavior of haunches beams under statically loading, a novel finite element (FE) model is introduced in this article. The FE model developed provides for the analysis of three sequences of RCHBs with various variables (haunch angle, haunch weight, and point load distance). To validate the efficacy of used computational methods involving load capacities, load-deflection graphs, and crack patterns of haunches beams, the FE model then was confirmed vs an experimental work available in the literature, which demonstrated a strong agreement.
