LOAD TESTS OF LARGE WOOD-CONCRETE BEAMS

This report documents a series of experimental load tests on thick layered wood connected composite beams. The research of the thick layered beams is a precursor to possible future research thick layered wood-concrete bridge deck systems. Experimental results are given for two beams referred to as the wide beam specimens, and four beams referred to as the deep beam specimens. The results of the load tests are presented in terms of the measured beam deflections and the horizontal slip between the wood and concrete layers. Results for the loadings show that a low to moderate percentage of potential composite action was achieved. For the deep beam specimens the degree of the composite action observed ranged from 54.22% to 84.22% of that theoretically positive if the layers were fully bonded to each other. The results suggest that with proper construction and control of creep, the mixed wood-concrete construction for deep beams is feasible.
