A 4 2 M Long Restrained Beam Is Carrying A Superimposed Dead Load Of 89 Kn M And A Superimposed Live Load Of 79 Kn M Bot 1 (42.48 KiB) Viewed 39 times

A 4.2 m long restrained beam is carrying a superimposed dead load of 89 kN/m and a superimposed live load of 79 kN/m both uniformly distributed on the entire span. The beam is 400mm wide and 650 mm deep. At the ends, it has 4-20mm main bars at top and 2-420mm main bars at bottom. At the midspan, it has 2-20mm main bars at top and 3 - 20 mm main bars at bottom. The concrete cover is 50 mm from the extreme fibers and 12 mm diameter for shear reinforcement. The beam is considered adequate against vertical shear. Given that f'c = 27.60 MPa and fy = 345 MPa. A. Determine the nominal shear carried by the concrete section using detailed calculation. B. Determine the required spacing of shear reinforcements from detailed calculation. Express it in multiple of 10mm. C. Determine the location of the beam from the support in which shear reinforcement are permitted not to place in the beam
