Which risk sharply increases when weld quality is substandard during steel column splicing in high-rise construction?

💡 Explanation

When welds lack sufficient fusion depth or are riddled with inclusions, brittle fracture risk increases because the material's ability to deform plastically is compromised, leading it to snap under sufficient tensile force. Therefore, brittle fracture under tension results, rather than corrosion, buckling or shear failure, each requiring distinct weld defects and environmental or operational conditions.
