Timber-concrete composite T-beams were fabricated and tested to destruction. Unreinforced precast concrete slabs were glued to timber beams using an epoxy compound resulting in a T-section with the concrete serving as the flange and the timber serving as the web. Using an equivalent all wood transformed section gave good experimental agreement for the neutral axis position and curvature in the test beams but poor agreement for deflection. Four beams failed in sliding shear at the high shear region while one beam reached the full flexural strength of the composite section. It was shown that wood-concrete bonded T-beams may carry substantial loads and function as true composite beams.
