E ect of Wind Force on Continuous Post-Tensioned Trapezoidal Box Girder Under Di erent Radii of Curvature

Abstract

A bridge is a structure providing passage over an obstacle without closing the way beneath. Also they gain international importance as they are essential part of any road and railway network. With development of advanced technology in struc- tural engineering, long span bridges very with bridges having large span to depth ratios are built in structural steel, prestress or post-tensioned concrete. It have excellent riding characteristics that minimize tra c vibrations, torsional rigidity and strength which results in stable, dynamic, long lasting and elegant bridges. In this paper, analysis of a two cell continuous post-tensioned trapezoidal box girder bridges is presented by varying radii of curvature (0m, 50m, 75m, 100m, and 125m) using fnite element-based software (MIDAS). Also analysis of a two cell continuous post-tensioned curved box girder to evaluate e ect of wind force at di erent heights above ground level.
