A corrugated aluminum box culvert with rib stiffeners on the outside was instrumented for strain and deflection measurements that occurred during the backfill and live load. Measured strains were converted to stress, moments and thrusts. Deflections were calculated from bench mark measurements. Soil displacement were measured using four rod extensometers placed around the culvert. Calculated moments, thrusts and deflections are compared to results obtained from the finite element computer program CANDE. Hyperbolic models are employed for the backfill material and the construction sequence is simulated as closely as possible. Symmetrical and unsymmetrical live load are examined. Soil elements are assumed to be fully bonded to the culvert-beam elements as no interface element was utilized. Advisors/Committee Members: Sargand, Shad M.
