| Abstract: | The problem on calculating the effective length for a column in a braced steel frame it discussed in this paper.An analytical modcl.based on the analysis of basic instability configurations of frameworks,for calculating the effective length of an arbitrary braced frame column is proposed and formulated.For the convenience of practical application,a simplified approach to the estimation of the effective length values of columns employed in rigid-joint steel frames is also presented. |
