The extended Mohr–Coulomb (EMC) fracture criterion was employed for finite element analysis (FEA). Uniaxial tensile test and three-point bending test were conducted to analyze the fracture behavior from the material scale and calibrate the fracture criterion. The test specimens consisted of the base metal, heat-affected-zone metal, and welding metal obtained from an ESW joint with a 590 N/mm<sup>2</sup> class steel. Subsequently, FEA was conducted for a biaxial tensile test to investigate fracture behavior at a structural scale and verify the feasibility and accuracy of the calibrated fracture criterion. The comparison between the results from the FEA and test suggests that the FEA based on the EMC fracture criterion can accurately predict fracture behavior but tends to overestimate the bearing capacity. Thereafter, the effect of axial force on column was quantitatively investigated. The results suggest that the existence of tensile axial force at column decreases the ductility of ESW joint and shifts the fracture locus from the welding metal to heat-affected zone. However, the force has minimal influence on the pop-in load. Finally, the feasibility of applying the current Japanese specifications designated for the 490 N/mm<sup>2</sup> class steel for the 590 N/mm<sup>2</sup> class steel was examined. The results indicate that the provision can serve as a safe and reliable guideline for the 590 N/mm<sup>2</sup> class steel as well.</p></div>","PeriodicalId":596,"journal":{"name":"International Journal of Steel Structures","volume":"24 4","pages":"882 - 891"},"PeriodicalIF":1.1,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13296-024-00855-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141347789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicate that the four models can track well the strength and stiffness of the specimens up to ultimate and predict well different failure patterns.

This research employs both an analytical approach and nonlinear finite element analysis to investigate the strength of cellular steel members under combined compression and major-axis bending. In the analytical approach, the strength interaction equation for cellular steel beam-columns incorporating an initial imperfection is derived using the principle of stationary potential energy. A total of 864 FE models covering practical configurations of cellular steel shapes are analysed to assess the analytical solution and the extension of AISC360 and EC3 strength interaction equations. Effects of the parent shape, web opening configuration, member slenderness, and load eccentricity on the member strength are investigated. The results show that the proposed analytical solution accurately predicts the capacity of cellular steel members under combined compression and major-axis bending. Also, the European Code EC3 strength interaction equation that adopts the refined elastic buckling equation specifically derived for the cellular steel members can accurately predict the strength of practical cellular steel shapes.
