Learning Outcomes
1. Demonstrate Knowledge and understanding, in principle of structural behaviour and make links between structural materials, structural applications and health and safety.
2. Apply knowledge to the design of simple structural elements.
3. Calculate the internal and external forces and stresses acting on or within a range of simple structural elements.
COURSEWORK
Q1 Draw the beam arrangement and calculate the reactions at both supports. Also determine and draw the shear force and bending moment diagrams for the following.
a) A simply supported beam with a span of 10m is subjected to a point load of 200KN at the midpoint.
b) A beam simply supported has a span of 6m. It carries a 100KN point load at a position 2m from the left support.
c) A beam simply supported has a length of 8m and carries a uniformly distributed load of 15KN/m.
d) Draw the shear Force and bending moment diagrams if the beam in (a) if a UDL of 20KN/m is additionally supported by the beam.
e) Draw the shear force and bending moment diagrams if the beam in (c) also carries in addition a point load of 50 KN at 2m from the right support.
f) Determine deflections in simply supported steel beams with point loads and a uniformly distributed load provided in (a) and (c). Also compare the effect of these deflections for steel and concrete.
Q2 Identify and describe different methods of supports for structures in general and how are these are applied to both steel and reinforced concrete structures.
Q3 Explore, explain and produce valid factors of safety for live loads, dead loads and imposed loads using current codes of practice and building regulations, a valid example can be utilised to illustrate this further.
Q4 Discuss design responsibilities under CDM regulations.

Q6 Explain the elastic bending theory. And find the second moment of area of the following sections
Q7 Find the centroid of the following section.
Q8 Define and explain Newton's three laws of motion. Also explain the following.
a) Pressure and stress
b) Compression and tension
c) Stress and strain.
