Abstract

The purpose of this project is to conduct a study comparing the effectiveness of different cross frame orientations in lowering the deflection of the main stringers of a bridge. Three different orientations of cross frames were researched; vertical, angled with the superstructure webbing, and halfway-angled. All of these were studied when the stringers were placed directly under the superstructure and when the superstructure was placed outside of the stringers. Analysis was performed in a program called SAP 2000 to find the deflections along the stringers under different loading conditions. The results showed that when the superstructure was oriented over the stringers, the angle of the cross frame with respect to the webbing made no difference in deflection. However, when the superstructure was located outside of the main stringers, the deflection of the bridge was lowered the closer the cross frames were to the angle of the webbing.
