The document summarizes the key aspects of column design according to BS 8110-1:1997, including: 1) It classifies columns as short, braced, or slender based on their effective length and provides design recommendations for each. 2) It describes how to calculate the effective length and minimum eccentricity of columns. 3) It explains how to calculate design moments for braced and unbraced columns, including additional moments from deflection. 4) It provides guidance on designing for shear forces and constructing an interaction curve for the combined effects of axial force and bending moments on a column.
