This paper presents an investigation on shear resistances of short beams using high performance fiber-reinforced concrete (HPFRC) composited normal concrete (NC). Total twelve short beams with identical span-length/depth ratio of 2 were tested under three-point bending. HPFRC and NC had their compressive strength of 80 MPa and 20 MPa, respectively. HPFRC layer was placed in extreme top or bottom fiber with various thicknesses; for each thickness, steel reinforcing-bar and no reinforcing-bar embedded inside beams were examined. The results of experimental test were evaluated and discussed.
