  1. Chapter 5 Introduction to Axially Loaded Compression Members

  2. Compression Members Chords of Trusses Columns Bracing Members Columns are straight vertical members whose lengths are considerably greater than their thicknesses

  4. Column Failure Modes Local Buckling Torsional Buckling Flexural Buckling (Euler buckling)

  5. Length, L Material, E Flexural Buckling (Euler buckling) Cross section, A or I or r End support condition

  6. Columns are Long and slender members subjected to an axial compressive force. • Buckling is Lateral deflection of columns • Buckling result in instability of columns, and causes sudden failure. • Buckling occurs when load P > Pcr the critical load

  7. Buckling Load of an elastic column is calculated using Euler Formula Dividing both sides by cross sectional area A And since the radius of gyration Euler Buckling Stress is the defined as Structural Steel Design by McCormac and Csernak, 5th Edition, Int. 2012

  11. For short columns , the failure stress will equal the yield stress. For intermediate columns , the member will fail by both yielding and buckling. The strength of long columns is predicted by Euler formula (elastic buckling control) Structural Steel Design by McCormac and Csernak, 5th Edition, Int. 2012
