Aims and objectives

This unit of study aims to provide you with the knowledge and skills required to analyse indeterminate structures using approximate methods and to design steel structures.
 
After successfully completing this unit, you should be able to:
1. Analyse indeterminate frames and trusses using approximate methods of analysis. (K1, K3, S1, S2)
2. Describe the material properties of steel. (K1)
3. Determine the ultimate tensile capacity of steel members considering both yielding and tensile fracture. (K1, K3, S1)
4. Determine the ultimate bending moment capacity of steel members considering both yielding and lateral buckling. (K1, K3, S1)
5. Assess shear capacity of beams and design web bearing stiffeners if required. (K1, K3, S1)
6. Determine the effective length of compression members in both braced and sway conditions. (K1, K3, S1)
7. Determine the ultimate capacity of compression members taking into account both yielding and buckling. (K1, K3, S1)
8. Identify the load paths in connections and classify the function of steel connections according to their moment carrying capacity. (K1, K3, S1)
9. Describe different welding techniques and classify different types of bolts and their installation. (K1)
10. Design bolted connections in shear, tension and combined actions. (K1, K3, S1, S2, S3)
11. Design welded connections and fastener groups. (K1, K3, S1, S2, S3)
12. Function effectively in small groups to design a simple steel structure considering different loading actions, constructability and structural safety. (K3, S1, S2, S3, A4, A7)
