Shear resistance of ultra-high-performance fiber-reinforced concrete
HighlightsA newly shear testing system to investigate shear resistance of UHPFRC was proposed.The shear related hardening behavior, accompanied by multiple crack formation was obtained.The shear resistances of UHPFRCs significantly depended on both the fiber volume and a/d.The shear strengths of UHPFRCs containing 0.5 and 1.5vol.% smooth fibers were shown to exceed the direct tensile strengths about 1.6 times.A theoretical model predicting the shear strength of UHPFRC based on the direct tensile strength and a/d was proposed.
AbstractThe shear resistance of ultra-high-performance fiber-reinforced concrete (UHPFRC) was investigated by using a newly proposed shear testing system. UHPFRCs displayed strain-hardening responses, in both shear and tensile testing, accompanied with multiple microcracks. The shear resistance of UHPFRCs was clearly influenced by their tensile resistance in addition to shear span to depth ratio (a/d). The shear strengths of UHPFRCs generally exceed the direct tensile strengths about 1.6 times. A theoretical model predicting the shear strength of UHPFRCs was proposed based on the tensile strength and a/d ratio.
