1 Chapter 4 Design of Tension Members Structural Steel Design, Fifth Edition, McCormac and Csernak, 2012 (International 1

2 Selection of Sections Loads to be carried Compactness Fit with other members Maximum connectability Structural Steel Design, Fifth Edition, McCormac and Csernak, 2012 (International 2

3 Bolted connection probable section: Angles Channels W or S sections Structural Steel Design, Fifth Edition, McCormac and Csernak, 2012 (International 3

4 Welded connection probable section: Plates Channels Structural Tees Structural Steel Design, Fifth Edition, McCormac and Csernak, 2012 (International 4

5 Code requirements to be checked

6 Additional Code Requirement AISCS D.1 : L / r < 300 – Ratio of unsupported length to least radius of gyration – Enough stiffness to control deflection and vibration – Not for rods Structural Steel Design, Fifth Edition, McCormac and Csernak, 2012 (International 6

7 Design process: (trial-and-error) 1.Estimate required area 2.Select a section from the AISCM  A provided 3.Check the section's strength 4.May try a slightly larger or slightly smaller section as required 5.Repeat the checking process Structural Steel Design, Fifth Edition, McCormac and Csernak, 2012 (International 7
