The aim of the work is to present the trend of the advancement of steel design code and practical approach of steel frame design from the current AISC-LFDR to the advanced analysis. As the trend of steel frame analysis method is from first-order elastic analysis to second-order inelastic analysis which is an advanced analysis. Methods. In this paper the comparison between the load - displacement curves of several structural analysis methods is presented. Case studies are considered to analyze by different methods and comparison of practical advanced analysis method with PROKON software. The case studies includes a two-story one bay steel frame and four bays of twelve-stories steel frame. The results of first-order elastic, elastic buckling, second-order and nonlinear analyses of an unbraced frame are compared and their difference is presents. The proposed software for advanced methods demonstrates the accuracy and the computational efficiency in predicting the nonlinear analysis response of steel frame structures.

This paper presents the comparative design procedures for steel frame elements using three different International design codes, viz. the American Institute of Steel Construction (AISC), the European Code (EC3) and the Russian Design Code (SP). It focuses on the resistance capacity of steel members subjected to different loads, such as tension, compression and flexure. It compares the formulation of all codes that identify their similarities and differences. The comparative study is performed for a compact rolled I sections with different slenderness and lateral bracing lengths. The results are presented graphically in different ways such as strength curves, Moment capacity versus lateral bracing length and normalized graphs. The comparative study shows that the resistance capacity specified by all specifications can be different for some considered cases. For compression member, SP specifications have higher capacity and economical approach. For flexural member, AISC gives higher capacity for inelastic region and EC3 gives higher capacities for elastic region but SP approach is lower for flexural capacity.

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). 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. It is essential for a steel designer using both SDCSS and EC3 to comprehend the basic differences between these specifications. 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. For various steel grades, member lengths, and 153 different European I/H sections, design buckling resistances and design compressive strengths are computed and compared. It is shown that there are at most 3% difference between the effective areas computed using both specifications. It is highly recommended that the change of cross section class be allowed while calculating design buckling resistances. 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.
