Evaluating Parameters of Bearing Capacity of Ring Footings

Abstract

Because of its durability, structural ring footings have been used under the maritime structure’s shallow foundations for many years. so, the efficacy and application of shallow foundations ring footings typically are little understood. These footings was tested for the bearing capacity of this research in a laboratory. The impact of ring depth and stiffness on the bearing capacities of ring footing models was studied in this respect. Ring footings design was based on the structural and geometry requirements. it was estimated that using structural rings would increase the support capacities of both soil-rings and soil-footing depth by 1.62 times. The behavior of a ring footing resting on (sand, clay, sand over clay, clay over sand) soil exposed to vertical stresses was investigated in laboratory experiments. A small-scale physical model was built and tested to achieve this goal. included an aluminum circular footing with a diameter of 100 mm and a d/D ratio of (0,0.33,0.5,0.67,0.95) to see how the d/D ratio affected bearing capacity along with different embedding depths to observe how they affect depth and footing size affected bearing capacity. Because the number of drilling and filling operations decreases as it varies from conventional foundations in that it has an increasing number of ring footings. By using the peripheral ring, it is possible to avoid excavating in adjacent construction sites subsurface soil, which reduces the amount of disturbance. This structure appears critical for expense and productivity given the potential advantages of using rings as feet. Meanwhile, further research into the adjacent foundations' bearing capacity and settling activities is needed to show their advantages to practical engineers
