Section A –Reinforced Concrete
QA1 Reinforced Concrete Beam (Total 50 Marks)
Figure Q.A1, details the beam and column layout of a reinforced concrete structure. Design and prepare bar bending schedule for the simply supported rectangular beam along grid line 2.
(i) Determine the maximum loading on beam (11 marks) (ii) Design the simply supported beam along grid line 2. (33 marks) (iii) Prepare a bar bending schedule for the beam designed in section A1. (i, ii & iii) Include the completed schedule with you Answer Book. (6 marks)
Design Information for Q.A1:
Durability and Fire: Exposure: Superstructure – mild Fire: 1 hour Loading: Dead Loading: Specific weight of reinforced concrete = 24 kN/m^3 Weight of suspended ceiling & services = 1.75kN/m^2 Brick/Block wall (2.4m height on all beams) = 4.1kN/m^2 of wall area
Imposed Loading: ( uniformly distributed loadings of Table 1, BS6399 –1:1996) Office (general use) = Category B Weight of removable partitions/fittings = 1.75kN/m^2 Materials: Concrete:^ Grade 35 (maximum aggregate size 20mm) Reinforcement: Main – high yield, fy = 460 N/mm^2 Links – mild steel, f (^) y = 250 N/mm^2
