CIVL2007 Theory and Design of Structures II Steel Component (27 April 2007) page 2 TOPIC 1: GENERAL PRINCIPLES AND DESIGN - LECTURE NOTES - Unless otherwise noted, all clauses cited in this lecture have been taken from the Hong Kong Code of Practice for the Structural use of Steel (2005) {otherwise known as HK Steel Code (2005)}. Design Aims The aims of structural design are to provide a structure with the following attributes (HK Steel Code 2005): 1. Overall stability against overturning, sliding, uplift or global buckling under the design loads. 2. Strength against collapse under normal loads and imposed deformations and strength during construction with an acceptable level of safety. 3. Integrity, ductility and robustness against abnormal loads from extreme events without suffering disproportionate collapse, in which alternative load paths may be established. 4. Fire resistance. 5. Serviceability under all normal loads and imposed deformations. 6. Durability. 7. Buildability. 8. Maintainability during its design working life. 9. Economy: The structure should fulfill the above requirements in an economic manner. Figure 1.1. Where exactly in Hong Kong is this construction site? What is being constructed? What are the different materials and how are they being used? CIVL2007 Theory and Design of Structures II Steel Component (27 April 2007) page 3 Design Methods The following are a list of different design methods ranging in complexity. 1. Simple Design Connections are pinned/flexible, bracings are needed to prevent sway....
