Abstract

In this study, cement mortar was sprayed on the shear span of the reinforced concrete beams wound with Vinylon fiber rope, and the loading tests were executed. The effect of sprayed mortar on the shear behavior of RC beams was investigated. The reduction factor of the shear capacity of shear reinforcement by the truss analogy was decided. The calculated maximum load evaluated as the sum of the reduced shear capacity of shear reinforcement and the shear-reinforcing effect of Vinylon fiber rope by the theory of a free body had the same tendency as the experimental maximum load. Sprayed mortar had only small effect on the failed shear span and the maximum load.
