handwritten answers)

1. Determine the area of main steel, As1, required for the beam assuming the following material

strengths: fck = 30 MPa and fyk = 460 MPa.

Design the shear reinforcement for the beam as well. Carry out a deflection check for the beam.

2. Design the shear reinforcement for the beam shown below, assuming it resists an ultimate shear

force at distance d from the face of the support of 250 kN. The characteristic material strengths are

fck = 25 N mm2 and fyk = 460 N mm

2.

3. Design the longitudinal and link reinforcement for the beam shown below assuming Class XC1

exposure. The beam is made of class C25/30 concrete of bulk density 25 kNm3 and grade 460

steel.

4. Design a pad footing which supports a column (200 x 200 mm) and subjected to axial

characteristic permanent and variable actions of 900 kN and 300 kN respectively ( fck = 25 MPa

and fyk = 460 MPa, soil bearing pressure 150 N//mm2).

5. Calculate the maximum variable load that the beam shown below can carry assuming that the

load is (i) uniformly distributed or (ii) occurs as a point load at mid-span.

6. Design the one-way spanning floor shown below for an imposed load of 4 kN mm2, assuming

the following material strengths: fck = 25 Nmm2, fyk = 460 Nmm

2. The environmental conditions

fall within exposure class XC1.

7. Calculate the maximum uniformly distributed variable load that the floor shown below can

carry.
