Analytical and Experimental Study of a Through Truss Bridge
The report presents the results of a field test on a through truss bridge. Both static and moving load tests were made, but only static test results are presented. The bridge was instrumented with numerous strain and deflection gages on the main truss members as well as on floorbeams, stringers, and on the concrete deck. Previously developed analytical techniques were used to relate theoretical and design assumptions to measured strains and deflections. In one technique, the truss was analyzed as an orthotropic plate. The plate equations were solved using a finite difference method. Various changes in the actual bridge configuration has to be made in order to be compatible with certain limitations of the analytical method. In general, measured strains in the bottom of stringers compared favorably with analytical values, but analytical floorbeam strains, although having in general the same distribution shape, were appreciably lower than corresponding measured values. analytical and measured deflections have better agreement. Measured strains and deflections were always much lower than design values. (Author)
