Abstract
Thesis Summary
Seven full-scale reinforced concrete corbel specimens were tested to study performance of steel fiber reinforced concrete corbels with and without fibers. The test variables were steel fiber content (Vf %) and shear span-to-depth ratio (a/d), with constant concrete compressive strength (fcu), area of main steel reinforcement (As) and presence of horizontal stirrups.
Both ACI Building Code provisions and Fattuhi equation agree with the test result specimen’s. One of the experimental test results with 1% fiber reinforcement was checked using ANSYS. Test results showed that, addition of steel fibers up to 2 percent improves both shear strength and ductility of the tested corbels, and results in a more ductile failure mode.
There is a considerable increase in the ultimate shear strength of steel fiber reinforced concrete corbels with the addition of steel fibers for specific range and. The test result showed an increase in the ultimate load up to 2% fiber content as shear span to depth ratio changed from 0.80 to 0.65.
