Abstract
This study investigates the bearing capacity of a strip footing featuring a modified Base angle V-shape, embedded in sandy soil .
Comprehensive experimental and numerical analyses were conducted to evaluate the effects of varying badr angles ( vertical angles) and the footing embedement depths on the ultimate bearing capacity (Q _u ).
the finding reveal show that the modified V-shape footings significantly enhances the bearing capacity compared to traditional strip footings.
Increasing the badr angle from 30° to 60° result in a remarkable maximum increase of 57 percentage in (Q _ u).
Additionally, an optimal depth-to-width ratio of 2 was identified , ensuring the best performance of a Nonlinear regression analysis provided a predictive model for estimating ( Q _ u ) based on badr angle and footing depth.
Findings from this research contribute to the development of efficient, reliable and safe foundation designs for various structures on sandy soils
