A machine learning regression approach for predicting the bearing capacity of a strip footing on rock mass under inclined and eccentric load

Frontiers in Built Environment, 2022
In this study, the Multivariate Adaptive Regression Splines (MARS) model is employed to create a data-driven prediction for the bearing capacity of a strip footing on rock mass subjected to an inclined and eccentric load. The strengths of rock masses are

BuckinghamPy: A Python software for dimensional analysis

SoftwareX, 2021
The Buckingham Pi (Π) theorem is useful in determining the dimensionless terms that describe a physical phenomenon. The number of these terms grows with the number of variables. The traditional approach in identifying dimensionless quantities for a given
