Abstract

This paper presents the dynamic response of simply supported steel railway bridges due to a train moving across the bridge. The finite element technique is used in the analysis. The train is modeled as a series of concentrated moving loads, and a bridge with a beam element. A train type "D" given in the Egyptian code of practice is used in this study. A computer program is developed to achieve the desired analysis. Actual cases of simple span, single Track steel girder bridges are analyzed. Natural frequencies and mode shapes of the investigated bridges are computed. The dynamic factor based on the deflection and the bending moment of these bridges, is also determined and plotted against the impact factor calculated from the empirical formula given in the Egyptian specifications of railway bridges. Different factors affecting the dynamic response of steel railway bridges, such as train speed. its acceleration, bridge span and damping coefficient of the bridge are studied.
