Abstract:

The dynamic response of single span curved I-girder bridges during construction was studied analytically. Parameters involved in the study are cross-frame shape, cross-frame cross section, cross-frame spacing and the radius of curvature. The main purpose of this research is to determine which parameters have the greatest influence on the dynamic response of curved steel I-girder bridges during construction. Attempts were made to establish the guidelines for cross-frame geometry so that forces and deformations induced under dynamic loads are minimized.
