Abstract

Checking for stability of columns and beams in braced frames is based on the elastic effective lengths. Simple design formulae. for checking the stability of the individual Pin-ended columns, are derived, where the effective length is equal to the line structure length. In this paper the problem of checking the stability of single braced frames, by using the equivalent column approach is considered. i.e the stability check of the total braced frame is replaced by stability cheeks of the individual Columns. Requirements necessary for the beans of a simple braced frame are sought, when the column is checked for stability using the elastic effective length.
