Question 1 A 6m span simply supported reinforced concrete beam carries a u.d. dead load of its self weight (based on 25kN/m3) + 10kN/m as well as a u.d. live load of 12kN/m. Assuming a beam section 250mm wide by 400mm deep, with d =350mm, design the tension reinforcement required to carry the mid-span moment, assuming fck=35N/mm2 and fyk=500N/mm2 Mark Question 2 In the assessment of an old building, a simply supported R.C. beam, with the section shown, spans 7m. The assessed loading is self weight + additional dead load of 12kN/m and live load of 10kN/m. Assume *fcu=35N/mm2, fyk=410 N/mm2 (use EC2 (m values for convenience). Compute the capacity and state whether the beam is safe to carry the above loads. Note: You will need to calculate fck from fcu Mark Question 3 Design a doubly reinforced concrete beam to carry a superimposed u.d. live load of 25kN/m over a span of 16m. The beam has a breadth of 300mm and an overall depth of 800mm. Assume fck=40N/mm2 and fyk=500N/mm2 Question 4 Design the reinforcement for the beam shown below. Assume a section of h=750mm, b=300mm, fck=35N/mm2, fyk=500N/mm2, cover=40mm, links=10mm.
