Effect of Sectional Modulus on Universal and Hollow Steel Columns Subjected To Flexure (original) (raw)

Abstract

The sectional modulus of rolled universal and circular hollow steel section columns in BS 5950(2000) was investigated in order to determine the safety of the available section modulus when subjected to flexure. The BS 5950 (2000) was evaluated in the light of Load Resistance Factor Design (LRFD) (1999) of the American Institute of Steel Constructions (AISC) due to their similarities. Results indicate that the safety levels of UC and CHS steel columns varies with the amount of sectional modulus available in flexure while the safety values to be used which depend extensively on column sections are predicted in each column type.
