Abstract
The parameter study of buckling behavior of steel built-up column under compression force is presented in this study. The shear deformation effects due to the bending moment and shear forces are considered for the H-shaped main members along the entire built-up column and batten member connecting double H-shaped main members. The parametric study is performed according to the length of the built-up column, the distance of the H-shaped main members and the number and type of cover plate for battens, respectively. The applicability of AISC design specification of normal and high tension bolted built-up column is investigated. The buckling loads for built-up columns are compared with those obtained from the analytic solution developed in this study, AISC specification, and finite element method based on the beam and plate element, respectively.
