Experimental investigation of shell foundations on dry sand

Abstract: Shells are usually used as structural elements in buildings. In Germany they showed remarkable resistance to the effects of bombing during World War II. About 1 decade later, the possibility of employing shells in foundation engineering was explored. Surveys of the literature indicate that shell foundations have been employed effectively in different parts of the world and were proven to provide an overall economical alternative to the conventional flat foundations. However, the geotechnical design of these fo… Show more

“…Reduction in total settlements ranging between 13.90% and 19.30% took place due to changing the bottom of footing shape from flat into elliptical with different configurations. Test results of group 3 along with the reference case (group 1) are shown in Figure (6). The load settlement curve trend for the flat and trapezoidal bottom footing cases is essentially the same, but with smaller measured settlements in case of trapezoidal bottom footing.…”

“…The study investigated the effect of varying the slope angle of the side of the inverted shell footing for three angles (15°, 30°, and 45°) and the embedment depth for two values (40 cm and 50 cm) on the change in settlement values due to applied load for the six sections of the selected footings (three sections for the shell footing and three sections for the traditional flat footings). Additionally, the efficiency factor of the shell footing was determined using Equation (1), as well as the settlement improvement factor according to Equation ( 2) [14]. The results obtained are presented as follows:…”

“…Hanna and El-Rahman [5,6] conducted an experimental assessment of the ultimate bearing capacity of triangular shell strip footings on sand, triangular shell footings have a greater bearing capacity and result in less settlement than conventional footings under the same stress circumstances. There were four distinct shell footing types employed, with peak angles between 60 and 180 degrees.…”
