Abstract It is a well established fact that the behaviour of columns as part of a structure is affected by the end restraints. The main aim of the current study is to develop a criterion of stability… Expand

In this paper, a versatile and efficient solution for the displacement function of a geometrical imperfect beam element under high axial load is derived.Expand

The choice of the global analysis method of a steel structure is essentially related to its sensitivity to second order effects. This sensitivity depends on the structural strength to the lateral… Expand

The concept of the effective length factor represents an important parameter with regard to the elastic buckling analysis. This concept makes possible computational of the elastic critical load using… Expand

This paper presents an alternative computation approach for the critical moment of lateral-torsional buckling of a simply supported steel beam with continuous lateral elastic restraint. The total… Expand
