Abstract. Cold-formed Steel (CFS), a sort of steel weighing lesser, suits to be a wise choice of material in the construction of steel structures. It has more benefits that indeed make CFS get famous. Effortless installation can be accomplished with the CFS. It also renders a factor that only a few materials show, that is, longevity. Corrosion does not affect the CFS. Employing under moderate loads, CFS finds to be economically feasible when compared with hot-rolled steel. It can be used as compression members comprising single or built-up members. Since a single member cannot sustain the heavy load, the built-up members can be utilized. Open and closed sections are the two sorts of built-up profiles and these profiles show diverse buckling characteristics. This paper lays out a clear outline of the research works done on providing design recommendations to the codes by employing diverse built-up sections. It is reviewed by categorizing the investigated research works based on the kind of CFS sections chosen by each researcher. It was evident from the study that after validation, many researchers have done parametric study on CFS built-up columns to assess the accuracy of the design strength prediction by code specifications. Many codes failed to estimate the section’s ultimate capacity accurately as there are no specific design equations.

“…El Aghoury et al [8], [9] investigated the behaviour of battened columns under eccentric compressive axial force. It was observed that for short battened columns, the design predictions according to EN 1993-1-3 [1] and AISI S100 [2] were in good agreement with experimental and numerical results.…”

Built‐up cold‐formed steel (CFS) columns are extensively used when single cold‐formed steel elements are not able to fulfill the established requirements in terms of load‐bearing capacity. For hot‐rolled steel laced and battened columns, the EN 1993‐1‐1 presents specific design provisions. However, no specific design guidelines are provided for CFS laced and battened columns. The investigation on this type of built‐up elements is scarce, requiring extensive research to assess if the hot‐rolled design methodologies are also suitable for cold‐formed steel elements. In this investigation, experimental and numerical results are presented for CFS battened columns comprising C and Σ channels. Assessing the composite action between the individual shapes connected by the batten plates was one of the objectives of this investigation. The predominant buckling modes were analyzed considering the influence of batten plate spacing and the number of fasteners per plate. Based on the obtained experimental results finite element models were developed to further assess the influence of key governing parameters. The observed axial strengths are compared with design strengths determined according to the Eurocode assessing the suitability of the design methodologies.

“…The behaviour of a column with different cross section subjected to eccentric load has been studied such as circular tubular column [4], elliptical hollow column [5], square and rectangular hollow columns [6], and the battened column composed of L-profiles under uniaxial and biaxial loads [7]. The tube column using the outer encasing thin-walled steel tube containing the other tubular columns is researched in [8], where the average confining stress in the mentioned columns with small eccentricity is approximately equal to that in columns under axial load.…”

The purpose of this paper is to determine a critical load for a nonuniform circular steel tube under eccentrically axial load. The circular tube has variable cross section at flattened ends with existing holes used for connection between members. Three different cases of eccentricities are studied with the drilled holes either on the same side or on the opposite side of column axis. The critical load is calculated from the differential equation of deflection curve which is solved by the power series and Runge-Kutta method. In addition, the loading tests were performed on a total of 180 specimens with different diameters, slenderness, and connection. The calculated results are compared and shown in a good agreement with those obtained from the experimental results. The results also show that the critical load decreases rapidly even at a small value of eccentricity and thus may have a significant effect on the load-carrying capacity.
