Fig 13.opju: Correlation Matrix for Concrete-Filled Steel Tube Variables

An origin project file containing a correlation coefficient matrix for variables in a concrete-filled steel tube study. The 70.5 KB file shows relationships among outer steel tube size, tube thickness, member length, steel yield strength, concrete strength, ultimate load, and displacement. It was authored by Hongtao Zhang and last updated on June 1, 2026.

Use Cases

• Calculate correlation coefficients between material properties and structural performance based on the described variables.
• Train regression models to predict ultimate load based on tube dimensions and material strengths mentioned in the description.
• Analyze the influence of member length on displacement using the correlation matrix.
• Validate finite element models of composite columns against the experimental relationships suggested by the data.

Strengths

• File size is precisely 70.5 KB, indicating a focused and manageable dataset.
• The description explicitly lists seven key structural and material variables for analysis.
• Dataset is licensed under CC-BY-4.0, allowing for open sharing and modification.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (70.5 KB), indicating limited scope.
