This invention relates to the field of shear capacity testing for hinge joints in hollow concrete slab bridges. It provides a method for testing the contribution of hinge joints to shear capacity in hollow concrete slab bridges, addressing the prominent issue of hinge joint defects during operation, such as cracking, damage, and water seepage, which in extreme cases can lead to "single-slab stress" in the hollow slab.

Based on the principle of superposition of components, a formula for calculating the shear capacity of the hinge joint is derived, quantifying the contributions of concrete and shear reinforcement to the shear capacity of the hinge joint.
