9. What is Structural Steel?
Structural steel is a standard construction material, made from specific grades of steel and formed in a range of industry standard cross-sectional shapes (or ‘Sections’). Structural steel grades are designed with specific chemical compositions and mechanical properties formulated for particular applications.

30. Simple structure
Assume structure is constructed of elements connected by pinned connections
Lateral resistance is provided by bracing, shear walls or lift core

31. Continuous structure Elements connected rigidly (moment resisting)
Lateral resistance provided by moment resisting frame

43. Common structural form applications of different sections:
UB – flexural members: Very efficient sections for resisting bending moment about the major axis
UC – axial member: capability to resist axial loads with high radius of gyration about minor axis to prevent buckling
PFC – Used for beams, bracing members
Angles (equal/Unequal) –– Used for purlins, truss members and bracing members.
Hollow sections – Used for truss members, ties and bracing members
