Approximate Formulae for Determining the Effective Length of Steel Columns to BS 5950

This paper presents approximate formulae that may be used to determine the effective length of steel columns designed to BS 5950. These formulae give the designer an alternative to the graphical method given in Appendix E of the Code. The approximate formulae are normally accurate to better than the second decimal place. This approach follows the development of simple computer routines for incorporation into column and frame design programs. A.G. Smyrell
