- Abstract:
-
According to the plastic theory of steel fiber concrete, the yield conditions of rebar, concrete and steel fiber concrete were determined, and the oblique section failure mechanism of steel fiber reinforced concrete beam with two displacement parameters was established, and the upper limit theory of plastic analysis was applied to derive the function expression of shear failure load of oblique section by energy method, and the limit load was obtained by optimizing and solving it. By adjusting the layer thickness of steel fiber concrete, the calculation formula is applied to the ultimate load calculation of the oblique section shear failure of ordinary reinforced concrete beams, reinforced steel fiber reinforced partial concrete beams and reinforced steel fiber reinforced full-section concrete beams. The example calculation shows that the calculation results are in good agreement with the experimental results, which proves that the calculation theory and method are correct.
