Guidelines:
? Assume any data if missing.
? Maintain neatness as it has weightage and write everything clearly on A4 pages.
? Consider fcu= 30 N/mm2, fy = fyv = 460 N/mm2, moderate exposure condition and 1.5
hour of fire resistance for all the questions.
? Use B.S 8110 for all your calculations and references.
? Draw the structural detailing after designing each member for all the questions.
? Unit weight of concrete as 24 kN/m3
? The values of live load 1.0 + (W/500) (Last 3 digits of your id), for example:
14J123456, then 1.0+(456/500) = 1.912 kN/m will be the load.
Q1. A simply supported reinforced concrete beam needs to be designed with the following
details:
Size of Beam: 250 mm x 600 mm.
Effective length of Beam: 8 m.
Dead Load excluding self-weight of Beam: 8.5 kN/m
Live load: 5 + (W/500) (Last 2 digits of your id)
Reinforcement: 25 mm bars and 8 mm stirrups
Effective cover to compression reinforcement: 25 mm
i.
Design the beam and find out the number of bars required.
ii. Design the beam for shear.
iii. Check for deflection.
iv. Draw the detailing of beam.
Q2. Figure 1 shows the floor plan of a proposed G+2 office building. It consist of one-way slabs
spanning between beams on grid lines A, B, C and D. At this stage as a structural engineer you
should design end span of the slab with Leff = 3 m, considering the design loads for the floor
(excluding the self-weight) includes a superimposed dead load (SDL) of 2 kN/m2 to account for
finishes, ceiling etc and live load 6 + (W/500) (Last 2 digits of your id). In addition, a 0.6 kN/m
wall load is applied around the building perimeter and on the beams located internally. Consider
the ends of the slab to be simply supported. Design the flexural reinforcement in the middle of
the end span, check for shear and deflection for the slab according to BS 8110 code provisions.
Consider the overall depth of slab as 180 mm and 12 mm bars along both directions.
Figure 1
Q3. Based on the design load of slab calculated in Q2, calculate the design loads of beams B1
and B2 shown in figure 1, by considering the mass of the beam as 1.5 kN/m run.
Q4.a. Enlist the reasons for adopting factor of safety in calculating the design load for the slab.
b. What the value of k indicates in the calculation for area of steel and what if the value is k>0.156.
c. In the calculation of deflection, if it exceeds the limiting value then what are the steps to be
taken in the design to limit the deflection?
