The Definition of a Short Composite Column

Document Type: Proceeding Paper

Part of: Composite Construction in Steel and Concrete II

Abstract:

A `short' column in composite construction is defined as one which can be designed for its cross-section strength alone without the need to consider stability effects. An extensive study has been made of the behaviour of braced composite steel and concrete composite columns for a range of cross-section types, slenderness ratios, initial imperfections, loading eccentricities and ratios of applied end moments. The results of this study have enabled the combination of parameters that determine a `short' column to be established. A simple design expression is proposed that gives good agreement with the results of the theoretical study using only a minimum number of parameters.
