| Abstract | ||
| The behavior of the strip footing on sand was deeply studied in many publications. They were trying to improve this behavior through many techniques. These improvements include the using of geogrid and geotextile reinforcement, skirts on the sides of the footing to elongate the contact surface of the footing with soil. None of these studies had implemented in the effect of the contact shape of the footing on its behavior. In this present experimental study, it is intended to observe the behavior of the convex strip footing on sand with different strip footing contact shapes. A series of experiments using different convex strip footing contact shapes, are carried out on sandy soil. The results showed that the increase in the strip footing contact areas, did not increase the bearing capacity, but decreases the ultimate bearing capacity load from about 30% to 60%. Also with sever convex curve, the ultimate load decreases seriously. | ||
