1.Concrete Mix-Design Feature Importance
Structural Engineer · 2026
This HappyCAD dashboard provides a structural engineer with data-driven material inputs for finite element analysis by analyzing concrete mix-design variables across 1,030 observations. The executive readout clarifies that curing age and water-to-binder ratio are the actual primary drivers of compressive strength, accounting for 62.4% of total importance, while a horizontal bar chart disproves cement-centric assumptions by ranking age highest with a mean SHAP importance of 7.77. Finally, a cement dependence plot displays a smoothed LOWESS curve illustrating the non-linear relationship between cement dosage and strength, explicitly noting where the taper begins at approximately 355 kg/m³.
What it shows:
Data-driven feature importance analysis corrects systematic errors in finite element analysis models by identifying true material strength drivers.
