What is it about?
This paper presents experimental and numerical studies on vertical stress distribution beneath circular footings on sand. Reduced-scale laboratory tests were conducted using soil stress transducers to measure vertical stresses at different depths under circular footings of various diameters. Finite element analyses were performed to validate the experimental results, modeling sand as a non-linear elastoplastic material. The study compared the results from laboratory tests, numerical analysis, and theoretical solutions. While the vertical stress distribution showed similar characteristics across all methods, some differences were observed and discussed. The research provides insights into stress distribution in sand beneath circular footings, which is crucial for geotechnical engineering applications.

Why is it important?
This research is important because: It provides valuable insights into the vertical stress distribution beneath circular footings on sand, which is crucial for geotechnical engineering applications such as foundation design and soil stability analysis. The study combines experimental, numerical, and theoretical approaches, offering a comprehensive understanding of the stress distribution phenomenon and allowing for comparison between different methods. The findings can help improve the accuracy of stress predictions in soil mechanics, potentially leading to more efficient and safer designs for structures built on sandy soils. The research contributes to the ongoing efforts to refine and validate existing theoretical models used in geotechnical engineering, which is essential for advancing the field and improving construction practices. Key Takeaways: • Vertical stress distribution beneath circular footings on sand shows a consistent characteristic form across all methods (experimental, numerical, and theoretical), with stresses decreasing as depth increases. • The study employed a multi-method approach, including reduced-scale laboratory model tests, finite element analyses (both 2D and 3D), and comparison with Boussinesq's theoretical solution. • While the general trend of stress distribution is consistent across methods, some differences were observed between experimental, numerical, and theoretical results, highlighting the importance of using multiple approaches to obtain a comprehensive understanding of soil behavior under load.
