Optimal Design of Ring Footing on Reinforced Sandy Soil under Eccentric-Inclined Loads

Title: Experimental Study on Geogrid-Reinforced Sandy Soil for Ring Footings Under Eccentrically Inclined Loading Description: This dataset/study provides comprehensive experimental results regarding the structural performance of ring footings resting on geogrid-reinforced sandy soil. The research specifically addresses complex loading conditions, including eccentrically inclined loads, which are critical for structures such as tower foundations, silos, and offshore supports. Key Parameters Evaluated: Reinforcement Length Ratio (L/B): Investigated up to L/B = 5. Spacing Ratio (Z/B): Analyzed between 0.25 and 1.25. Number of Geogrid Layers (N): Tested up to N = 4 and beyond. Loading Conditions: Eccentricity ratios (e/B) up to 0.16 and inclination angles (α) up to 15°. Main Findings: The data identifies the optimal reinforcement configuration (L/B=5, Z/B=0.50, N=4) which significantly enhances bearing capacity by approximately 200% and improves tilting resistance. The results highlight the limitations of excessive layering and improper spacing on soil-reinforcement interaction. Affiliation: College of Dentistry, University of Baghdad, Iraq.
