LOCAL BUCKLING AND SECTION CLASSIFICATION 8 LOCAL BUCKLING AND SECTION CLASSIFICATION INTRODUCTION Sections normally used in steel structures are I-sections, Channels or angles etc. which are called open sections, or rectangular or circular tubes which are called closed sections. These sections can be regarded as a combination of individual plate elements connected together to form the required shape. The strength of compression members made of such sections depends on their slenderness ratio. Higher strengths can be obtained by reducing the slenderness ratio by increasing the moment of inertia of the cross- SECTION . Similarly, the strengths of beams can be increased, by increasing the moment of inertia of the cross- SECTION .
