The shear forces acting on a beam are resisted by the stirrups together with the concrete. At the dimensioning this reinforcement, it is first necessary to determine the portion of the shear force supported by the concrete. For the calculation model 1, defined by NBR 6118, the portion of the shear absorbed by the concrete in a bended section is given by the following formula: In view of this, determine the value of Vc0 for a beam of width equal to 12 cm, useful height of 32 cm, executed with C35 concrete. ALTERNATIVES a) 36.9 kN b) 51.6 kN c) 122.9 kN d) 175.5 kN e) 73.4 kN
