Description
Summary:Footing foundation has been worldwide used in resisting light to medium load of structures. Footing's design has to consider the bearing capacity and the settlement of soil below. This research focuses on the investigation of the effect of skirt on circular footing to improve the footing performance in resisting vertical load on clay soil. There are nine samples of circular footing tested in vertical load system in laboratory in the diameter of 75 mm, 100 mm and 150 mm with length of skirt 100 mm and 150 mm on clay by keeping the similar water content and compaction method. The results show that the skirt effectively reduces the foundation settlement on clay which is observed on similar load 1 kN. The observations on L/D ratio on similar diameter also show that the higher L/D ratio the smaller settlement. On the observations of settlement 3 mm with similar diameter show that the longer the skirt the higher load retained by footing.
