The purpose of this study is to investigate effect of axial loads on deep RC beams. Toward this goal, deep RC beams having different shear span-to-depth ratios are fabricated and bending tests are performed on the beams applied with different magnitudes of axial loads. From the tests, strains on various locations, beam deflections, beam compression and shear strains are obtained. The experimental results show that, for the most of the tested beams, failure due to shear is occurred in the axially loaded deep RC beam and the axial load works beneficially to structural performance. However, when the shear span-to-depth ratio is sufficiently small and the large axial load is applied, the beam is failed earlier than as expected due to bearing failure.
