Comparison of Design Guidelines for Hot‐Rolled I‐Shaped Steel Compression Members according to AISC 360‐16 and EC3

Abstract

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.

Axial compression behaviors of steel shear-keyed tubular columns: Numerical and analytical studies

“…An analogous procedure has been used to draw the results with CSA S16-19 [105] and AISC360-16 [106] that adopt a resistance factor of 0.90 [107], overestimating 90 and 96 outcomes. Similarly, the GB50017-2017 standard [79] overestimates 104 results, with 𝛼 1 , 𝛼 2 , and 𝛼 3 of 0.65, 0.965, and 0.3.…”

Experimental Comparison of the Known Hypotheses of the Lateral Buckling for Semi-Slender Pinned Columns

“…Naseri et al (2020) presented an experimental study into the buckling behavior of Glass Fabric-Reinforced Polymer (GFRP) cylindrical shells subjected to axial compression load. Pinarbasi et al (2020) dealt with the Turkish Building Code for Steel Structures replaced with a more rational Specification of Design and Construction of Steel Structures (SDCSS), which was prepared based on the American steel design specification (AISC 360-16). Qays and Al-Zuhairi (2020) discussed the idea of using slender Reinforced Concrete (RC) columns with crossshaped (+-shaped) instead of square-shaped columns.…”

Technical Buckling, Stress and Strain Simplified Analysis of Semi-Slender Thin-Walled Cylindrical Pinned Column

“…It was concluded that the GFRP cylindrical shells showed the full-buckling strength and had local buckling failure mode. Pinarbasi et al (2020) dealt with the Turkish Building Code for Steel Structures replaced with a more rational Specification of Design and Construction of Steel Structures (SDCSS), which was prepared based on the American steel design specification (AISC 360-16). European steel design specification (EC3) was also widely used in Turkey.…”
