| "The fracture of stirrups due to concrete expansion has been reported on some bridge piers affected by the alkali silica reaction in Japan. RC beams with stirrups cut off at bent corners were tested to investigate their shear resisting mechanism. The test results indicated that the shear capacity of RC beams with damaged stirrups was reduced by approximately 20%; this reduction was induced by a decrease in the shear strengthprovided by not only stirrups but also concrete. In addition, the loss of confinement due to stirrups made it difficult to sustain the truss action, but contributed to the development of the arch action." |
