Flexural and Torsional Moment of Clamped RC Curved Beam: A Parametric Study

Abstract

A both-end fixed curved beam is a statically indeterminate structure according to the structural boundary condition. Since the center of gravity of loads and reactions to one side of any section does not lie along the axis of the beam, it is subjected to torsional moment, in addition to bending moment (flexural moment) and shear force. They are capable of exchanging loads through the combined action of twisting and stretching compared to a straight beam. The difference in analysis and design between the beams curved in plan and the straight beams is mainly due to the presence of torsional movement induced by the vertical load. This paper deals with the distribution and variation of flexural and torsional moment developed in the curved beam with different geometric parameters such as radius of curvature and depth to width ratio of the beam. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
