Unified probabilistic model for axial strength of concrete-filled aluminum alloy tube columns with circular and square cross-sections

Key Points

• Axial strength predictions achieve a high accuracy rate, enhancing design reliability.
• Results indicate an R-squared value of over 0.85, showing strong correlation between predicted and actual strengths.
• Analysis employed a unified probabilistic model focusing on both circular and square cross-sections, providing versatile applications.
• This model may enable better structural safety assessments for concrete-filled aluminum alloy columns.
