Practice Problem 4.2 A rectangular beam has a width of 260 mm and an overall depth of 470 mm. Concrete cover is 60 mm from the centroid of bars. Concrete compressive strength, fc = 21 MPa. Steel yield strengths are 415 MPa for longitudinal bars and 275 MPa for hoops. Determine the shear strength provided by concrete using simplified calculation a) If the beam is subjected to shear and flexure only. b) If the beam is subjected to axial compressive force, Nu= 80 kN.
