simply supported reinforced concrete beam of rectangular section is hung on the left end by a 400mm square post working in tension, as shown in the figure below. The beam supports a uniform dead load (DL) gf 100 KN/m (excluding its own weight) and upiform live load LL) of 40KN/m. The beam is reinforced with 025 longitudinal rebars with 40mm cleat cover to the stirrups. Material properties: fy 420 MPa, fe 25 MPa. Beam dimension b 400mm and h 600mm....

The reinforced concrete beam shown in Figure-2 is to be subjected to the following uniformly distributed loads over the entire length: DL = 14 kn/m (including self-weight) and LL = 20kN/m, fc = 32 MPa. For architectural reasons the beam width is set at 500 mm. Determine the effective depth required if ku = 0.25 for the section of maximum positive bending moment. Then design the reinforcement required. zin Figure-2

The following figure 1(a) shows a part of a reinforced concrete building in a school. The structure consists of precast concrete hollow slabs that rests on the 10.8m long two reinforced concrete beams. The beams are supported on reinforced concrete columns. It is given that, on the top surface of the hollow slab, there will be a concrete screed with 50 mm thickness (assume density of concrete screed is 25 kN/m). In addition, there will be tiles that weigh 0.05...
