This study aims to investigate experimentally mechanical characteristics of S-CFT deep beam under bending-shear through symmetrically three-point loading test method with a constant axial load. Selected test parameters are shear span and the width-to-thickness ratios, which are ranging from 1.0 to 1.5 and 62.5 to 200, respectively. As the results, observed failure modes of the specimens with width-to-thickness ratio being 200 were local buckling of steel tube associated with shear failure of in-filled concrete between two supports. No effect of the constant axial load on bending-shear capacities can be found. The experimental strength of the specimens with shear span ratio between 1.0 and 1.5 can be predicted by the accumulative strength being composed of RC deep beam and web steel plate.
