Consideration of Slenderness Effect in Columns
www.ce.memphis.eduComments on Axially Loaded Columns • A column might be considered short under some load conditions and end conditions, slender under others. • Columns braced against side sway have effective length between 0.5L and L. Columns not braced against side sway always have effective lengths greater than L. • High strength steel and concrete make ...
Module 10 - NPTEL
nptel.ac.inAxially loaded columns also need to be designed keeping the provision of resisting some moments which normally is the situation in most of the practical columns. This is ensured by checking the minimum eccentricity of loads applied on these columns as stipulated in IS 456. Moreover, the design strengths of

www.towernx.comDeWolf(13) and Thambiratnam(14) compared methods of designing building columns to test data. The AISC method for designing axially loaded base plates defines the critical section as being at .95 times the depth of the structural members for shapes of rectangular cross-section such as wide flanges and tubes.
