Flexural strength of cold-formed steel built-up box beam with self-drilling screw connections: an experimental assessment

Key Points

• To assess the flexural strength of cold-formed steel built-up box beams using self-drilling screw connections.
• Conducted flexural strength tests on cold-formed steel box beams.
• Utilized self-drilling screws for beam connections.
• Measured the load capacity and deformation characteristics.
• Determined the maximum load capacity of the beams under flexural loading.
• Analyzed failure modes for beams with different screw connection configurations.
