Title: DYNAMIC ANALYSIS OF GIRDER BRIDGES
Accession Number: 00494747
Record Type: Component
Availability: Find a library where document is available Abstract: This paper deals with the calculation of dynamic loads in girder bridges. Three major elements are considered: vehicle dynamics, road roughness, and bridge dynamics. The parameters representing the road profile and axle weights are treated as random variables. The statistical models are established on the basis of the available test, measurement, and analytical data. The mathematical equations relating forces and deformations are formulated, with the system of equations solved by a numerical integration method. Using the Monte Carlo technique, a procedure is developed for simulation of the dynamic load spectra. The approach is demonstrated on a typical steel girder bridge. The resulting distribution functions of the dynamic load are presented on a normal probability scale.
