Chapter 4 Design of Slender Columns - Engineering

Slender Columns 4.4 may be used to establish conservative values of k for braced columns2. 4.2.3 Radius of Gyration, r The radius of gyration introduces the effects of cross-sectional size and shape to slenderness. For the same cross-sectional area, a section with higher moment of inertia produces a more stable column with

Chapter 9: Column Analysis and Design

• Long, slender columns fail by buckling – a function of the column’s dimensions and its modulus of elasticity. - Buckling is the sudden uncontrolled lateral displacement of a column at which point no additional load can be supported. - Failure occurs at a lower stress level than the column’s material strength

and has now been extended to cover slender columns and prestressed concrete. An appen-dix for the structural design of foundations using limit state philosophy (as foreseen by ENVEC7), has also been included. It is hoped that this extended scope will be welcomed by practitioners. It is a helping hand not a substitute for the greater range in EC2.

λ>λr the shape is slender The above conditions are based on the worst width-thickness ratio of the elements of the cross section. The following table summarizes the width-thickness limits for rolled I-, H- and C- sections (for C- sections, λ= b / t f f. The web criterion is met by all standard I- and C- sections listed in the Manual.

12 Buckling Analysis - Rice University

Slender is a geometric concept of a two‐dimensional area that is quantified by the radius of gyration. The radius of gyration, r, has the units of length and describes the way in which the area of a cross‐section is distributed around its centroidal axis.
