Chapter 9: Column Analysis and Design
Chapter 9: Column Analysis and Design Introduction Columns are usually considered as vertical structural elements, but they can be positioned in any orientation ( diagonal and horizontal compression elements in a truss). Columns are used as major elements in trusses, building frames, and sub-structure supports for bridges ( piers). Columns support compressive loads from roofs, floors, or bridge decks. Columns transmit the vertical forces to the foundations and into the subsoil. The work of a Column is simpler than the work of a beam. The loads applied to a Column are only axial loads. Loads on columns are typically applied at the ends of the member, producing axial compressive stresses. However, on occasion the loads acting on a Column can include axial forces, transverse forces, and bending moments ( beam-columns).
The structure is adequately braced against lateral forces (e.g. wind and earthquake forces). Theoretical K-value: K = 0.7 Effective length: L e = 0.707 L P critical = π 2EI min /(0.707L) 2 = 2π2EI min /L 2 Examples: Concrete column rigidly connected to concrete slab at the base and attached to light-gauge roofing at the top.
