—vŽ| This paper presents the experiment of four tapered RC beams with and without stirrups. By comparing with tapered RC beams without stirrups, the shear resistance mechanism of the beams with stirrups was clarified. The location of the critical section was found to be increased due to the use of stirrups, which was related to the stirrup ratios as well. The evaluation method of shear carried by stirrups was also proposed by using the compression strut inclination and critical section at the occurrence of the main diagonal crack. The calculated value showed good correspondence with the experimental results.
