INELASTIC BENDING OF SINGLY REINFORCED CONCRETE BEAM SECTION *A trapezoidal concrete beam is casted with a compressive strength of about 20 MPa. The beam is reinforced with 3- 32 mm diamater bars in the tension zone with a yield strength of 275 MPa. The bar is located 100 mm from the bottom. Determine the nominal bending strength. Assume that the beam is symmetrical about the vertical axis with a depth of 600 mm, a top width of 500 mm, and a bottom width of 200 mm.
Design the reinforcement of a rectangular beam to resist a dead load moment of 200kN.m (including its own weight) and a live load moment of 300kN.m.
