Multiple column curves were also developed in Europe based mostly on the research studies conducted in European universities. Expressed slightly in a different form, the column curve used in AISC 360-16 is indeed identical to one of the curves derived by Bjorhovde. Taking the initial out-of-straightness as the mean value of 1/1470 of the column length, Bjorhovde also developed three additional column curves. Basic SSRC column curves assumed an initial out-of-straightness of 1/1000 of the column length. SSRC column curves were developed considering the effects of the (i) member length, (ii) shape and dimensions of the cross section, (iii) mechanical properties of the steel used in the production, (iv) magnitude and distribution of the residual stresses, (v) magnitude and shape of the initial out-of-straightness of the member, and (vi) restraints at the ends of the member. Considering the wide variability of the column curves, three strength curves, commonly called SSRC (Structural Stability Research Council) column strength curves, were developed by subdividing the band-shaped database obtained by Bjorhovde to obtain rational and reliable column strength criteria. According to Ziemian, many other researchers confirmed the findings of Bjorhovde. The comprehensive database developed by Bjorhovde for column strength curves pointed out the strong dependence of column strengths to the section shape, steel grade, and manufacturing process. Considered as a landmark study, Bjorhovde tested numerous concentrically loaded steel columns with different cross-sectional shapes, steel grades, and residual stress patterns. The design guidelines given in current specifications (such as those handled in this study) have been developed based on these valuable research studies. The вЂњclassical studies of Euler, Tredgold, Tetmajer, Considere, Engesser, von Karman, Shanley, and others until todayвЂќ have been accompanied by extensive numerical and analytical works. For a steel designer who uses both SDCSS and EC3, it is essential to comprehend the basic differences between SDCSS (or AISC 360-16) and EC3 in terms of their design rules and safety levels.ДЄs pointed out by Bjorhovde, many studies have been conducted on the strength and stability of steel compression members after the pioneering work of Euler in 1744. The use of EC3 in Turkey is known to continue particularly in the design of special steel structures. Since many steel structures constructed in Turkey and in different countries of Europe have been designed with the collaboration of Turkish and European design companies, European steel design specification, Eurocode 3: Design of Steel Structures (shortly EC3), has also been widely used in Turkey, especially before the publication of SDCSS. Prepared almost entirely based on the current version of the American steel design specification, i.e., the Specification for Structural Steel Buildings (AISC 360-16), the Specification of Design and Construction of Steel Structures (SDCSS) was published in 2016 and superseded BCSS. Realizing that BCSS has fallen behind most modern design specifications since it has not been updated regularly to reflect the changes in technology and design practice as well as to incorporate the advances in the state of knowledge, the Turkish Ministry of Environment and Urbanisation led to the development of a new up-to-date and rational specification for steel design.

In Turkey, the Building Code for Steel Structures (BCSS), which was based on the allowable stress method, was used for more than three decades in the design of steel structures. For the studied sections and steel grades, the resistance-to-strength ratios are found to be as high as 1.24 but not smaller than 0.907. It is highly recommended that the change of cross section class be allowed while calculating design buckling resistances.

It is shown that there are at most 3% difference between the effective areas computed using both specifications. For various steel grades, member lengths, and 153 different European I/H sections, design buckling resistances and design compressive strengths are computed and compared. This study aims to compare the design guidelines defined in AISC 360-16 (so in SDCSS) and EC3 for rolled I-shaped steel members subjected to axial compression thoroughly. It is essential for a steel designer using both SDCSS and EC3 to comprehend the basic differences between these specifications. European steel design specification (EC3) is also widely used in Turkey for the design of steel structures constructed with the collaboration of Turkish and European companies. Thirty-six years after its publication, Turkish Building Code for Steel Structures was replaced with a more rational specification, Specification of Design and Construction of Steel Structures (SDCSS), which was prepared almost entirely based on the current American steel design specification (AISC 360-16).
