1. A simply supported beam for an office building has a span of 6 m. Calculate the values of the design bending moments, MEd, assuming
a. The beam supports uniformly distributed permanent and variable actions of 5 kN/m and 6 kN/m respectively
b. In addition to the actions described in (a) the beam also supports an independent variable concentrated load of 20 kN at mid-span.

2. Figure 2 shows reinforced concrete floor slab panels arrangement with their supporting beams. The floor slab having thickness of 225 mm and to be designed to carry an imposed variable load of 3 kN/m2 plus floor finishes and ceiling loads of 1 kN/m2. Calculate the design load acting on the beam B1-C1.
Assume all the beams having a cross-section of 250 x 500 mm. Use unit weight of concrete, Υconc = 25 kN/m3.

3. A rectangular reinforced concrete beam has to support a design moment of 300 kNm. Determine the area of reinforcement required if the beam dimension is 250 × 500 mm (b × d), concrete strength fck = 25 N/mm2 and steel strength, fyk = 500 N/mm2.
4. A reinforced concrete beam is 250 × 500 mm (b ×d). The tension and compression reinforcements provided are 6H20 and 2H12 respectively. Determine the ultimate moment of resistance of the section, if fck = 25 N/mm2 and fyk = 500 N/mm2. The depth to compression reinforcement is 50 mm.
