ANALYTICAL INVESTIGATION OF RC CURVED BEAMS

Abstract

A RC curved beam is termed as a statically indeterminate structure according to the structural boundary condition and is subjected to a torsion moment. A suitable arrangement of rebarshould be used under such conditions. There are several factors that influence the ultimate torsional strength of a curved RC member, so universal theory is adopted for curved RC beam. The radius of curvature, span ratio, diameter of rebar and grade of concrete are the Parameters adopted and used here. The influence of these parameters changes the behaviour of RC curved beams. Analytical software ANSYS is used to find the optimum grade of concrete, diameter of rebar, depthof the RC curved beam. The maximum deflection of a curved RC beam is investigated analytically. The comparison of maximum deflection between conventional beam and curved beam are studied. From the present research, a three dimensional non-linear finite element models are adopted to investigate the behaviour and maximum deflection of RC curved horizontal beams.
