Section A –Reinforced Concrete QA. 1 Reinforced Concrete (50 marks) Details of the first floor slab, beam and column layout of a reinforced concrete structure are shown in Figure Q.A1. Design and prepare detailing sketches for the simply supported rectangular beam along gridline 3 in accordance with Eurocode 2. Beam dimensions are as follows: b=250mm; h=500mm. (a) Actions & Effects on Member (10 marks) Determine the Ultimate Limit State (ULS) shear force (VEd) and bending moment (MEd ) applied to the reinforced concrete beam. (b) Member Design (35 marks)  Determine a suitable size and number of reinforcing bars to resist the maximum sagging bending moment at mid-span.  Determine a suitable size and number of reinforcing bars to resist the hogging bending moment at the supports as required by EC2.  Determine suitable size and spacing for the shear links to resist the design shear forces along the beam length.  Verify the deflection of the beam. (c) Detailing Sketches (5 marks) Provide suitable sketches to illustrate the above design outcomes in preparation for detailed reinforcement drawing . Also complete the notes on the drawing. Use the attached General Arrangement drawing to complete the sketches and include with your Answer Book. Design Information: Actions on the Structure: Permanent Actions: Specific weight of reinforced concrete = 25 kN/m 3 Weight of suspended ceiling & services = 0.5 kN/m 2 Blockwork wall (2.8m height on all beams) = 6 kN/m 2 of wall area Variable Actions: Occupancy: Specific Use is ‘Office’ = 3.0 kN/m 2 Weight of removable partitions/fittings = 0.4 kN/m 2 Materials: Maximum aggregate size: dg = 20mm Grade of Concrete: C30/37 Characteristic yield strength of steel reinforcement: fyk = 500 MPa Cover: Exposure Class XC1 Figure Q.A1
