1. Introduction
Initial imperfections factor is an important aspect in determining ultimate strength of steel bridge compression members. Initial distortion and residual stress are most widely used in practical fields. In general analysis, material, boundary and geometry imperfection and also residual stress effects should be included in determining ultimate strength of real steel columns. Many studies in various cross section types of steel columns have proved that initial imperfection has important influence in making the ultimate strength decrease significantly. Schafer and Pekoz [1] have investigated the computational modeling of cold-formed steel members regarding geometric imperfection and residual stress. Study in the impact of global flexural imperfection especially applied in cold-formed steel column curve varied in initial displacement factor is continued project of the previous one [2]. Trahair and Kayvani also explored effects of excessive crookedness on capacities of steel columns using BS950 as basis of column design methods [3]. Some ultimate strength criteria in bridge specifications need to be evaluated and upgraded gradually to maintain the formulations accuracy in real steel members behaviour using recent numerical and experimental study. For example,
