Shear resistance mechanism of RC beams using U-shaped UFC has been examined. Experimental parameter was effect of thickness of formwork, presence of stirrup and shear span to effective depth ratio(a/d). The results showed that UFC permanent formwork enhanced the shear capacity of RC beams and the failure mode changed depending on a/d. Moreover, the shear capacity increased with increasing in thickness of formwork and presence of stirrup. Finally, the evaluation methods for shear carried by UFC permanent formwork in RC beams were investigated.
