ANALYSIS OF DISTORTIONAL STRESS IN CURVED I-GIRDER BRIDGES

A simplified means of determining more accurately the stress distribution in a curved girder system considering web distortion is presented. The distortional response of A single span curved plate girder bridge is determined utilizing a finite difference procedure. The analysis finds the maximum bending, warping and distortional stresses along each girder. A UNIVAC 1108 computer was used in the development of the simplified equations which relate the bending and warping stresses to the induced distortional stress. The program written in FORTRAN V, calculates the stress developed in a four plate girder system having any number of diaphragms along its span. /Author/TRRL/
