Columns & Bases
This module discusses the design of steel columns and their bases, detailing the procedures for single and built-up sections, managing axial loads and bending, and ensuring stability through effective lacing and battens. Additionally, it covers the appropriate design of bases and the critical design parameters to maintain safety and structural integrity under various loading conditions.

What we have learnt
- Steel columns are essential for supporting vertical loads and must be designed to prevent buckling and ensure serviceability.
- Different configurations and design techniques exist for single and built-up columns, each with specific considerations for load resistance.
- Lacing and battens are critical components for providing lateral stability in built-up columns, while base plates are vital for effective load transfer to the foundation.
Key Concepts
- -- Steel Columns
- Vertical load-bearing structures designed to withstand compressive forces, essential for maintaining the integrity of buildings.
- -- Lacing and Battens
- Structural elements used to connect individual column sections in built-up columns, providing stability and shear resistance.
- -- Slenderness Ratio
- A measure used to evaluate the risk of buckling in columns, calculated as the effective length divided by the least radius of gyration.
- -- BeamColumns
- Columns that must resist both axial loads and bending moments due to various forces acting upon them.
- -- Base Plates
- Flat steel plates used to distribute the load of a column onto a foundation, designed for specific thickness and attachment based on load requirements.
