a) Give results of tests carried out in class in the laboratory to show some performance characteristics of building materials
b) Show how building regulations are linked to material performance .
c) Show how unexpected results may occur even in otherwise safe materials Show what
testing and statical means could be used to separate a “rogue” result from one which has found sub-standard material.
d) Give an example of the reasoning behind the choice of a building material that is suitable for a particular critical part of a building.
e) Look at the effect of loading structural materials used in either beams or columns.
f) (i) Calculate the maximum load that can be applied to the centre of a reinforced concrete beam so that the deflection does not exceed 5mm The length of the beam between support is 5m the thickness of the beam is 1m and the width is 0.2m the Young’s Modulus is 200 x 106 MPa
(ii) A column is required to support a roof over an atrium. The column is 20m high with no supports in the middle but supports the centre of a pyramid shaped covering of the atrium. The weight of the roof is 5 tonnes and the column is cylindrical in shape with a constant diameter. It is made from the same concrete as outlined in (i) above. What is the minimum diameter needed for this column?
(iii) Compare two different materials which would be suitable for the same purpose as outlined in f ii) above and analyse their respective environmental impacts
