The shear strength of steel fiber-reinforced concrete beams Resistência ao cisalhamento de vigas de concreto reforçado com fibras de aço

摘要: 3), and the concrete compressive strength (40MPa, 60 MPa, or 80 MPa) were mains test variables studied. The beams had nominally identical cross-sections, effective depths, longitudinal transverse reinforcements. loads increased at 10 kN intervals until shear failure occurred, defined by yielding of first stirrup. ultimate observed in these tests compared to three empirical semi-empirical formulas proposed literature. Based on results it could be concluded that has no significant influence reduction load caused reverse loading. Reverse-loaded with fibers approximately same as without subjected normal loading, regardless concrete.
