Design Criteria for Steel I Columns Under Axial Load and Biaxial Bending,

摘要

The design code Canadian Standard S16.1-1974permits ultimate strength design steel H-columns subjected to axial load and biaxial bending moment. However,this is permitted only for sections in which the flange width to section depth ratio is equal to or greater than 0.8. In this paper a simple modification to the previous formulae is proposed which enables the restriction on flange width to section depth ratio to be removed so that they are also applicable to steel I-columns.
