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. The unbonded hinge joint specimen proposed in this invention eliminates the bonding force at the hinge joint interface by placing a thin film thereon. In this case, the shear capacity of the unbonded hinge joint specimen is borne by the shear reinforcement. This allows for the measurement of strain distribution along the entire length of the shear reinforcement, effectively preventing interference from closely distributed strain gauges on the bond between the shear reinforcement and concrete, and obtaining strain data of the shear reinforcement throughout the loading process. 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.
