To investigate whether previous proposed method can estimate bending capacity and shear capacity of steel rebar - glulam timber composite beam, 15 full-scale beam specimens, which a 3 rebar-embedded lamina was bonded as upper and lower outer layer of beam, were applied to loading tests for bending failure or shear failure. Moreover, push-out loading test of rebar in wood test pieces cut-out from one of the tested beam specimens was conducted to verify estimation method for shear capacity determined owing to shear failure around rebar.
