Analyses of Shell Footing in Layered Sandy Soil
Shell footing is economic alternative to long-established plain shallow foundations especially where heavy superstructural loads are to be transmitted to weaker soil. There are many shapes of shell footing such as circular, triangular (inverted and upright), conical, and cylindrical. In this paper, results of shell footing are presented. Models of upright and inverted triangular shell footings were developed in PLAXIS-2D software, which is a finite element-based software. Base to rise ratio (B/d or B/h) of the footing was varied. The results of the analysis were plotted as load settlement curves and ultimate bearing capacity were determined in each case. These were then compared with UBC of flat strip footing with similar conditions. The results indicated that shell footings have higher UBC than that of flat strip footing. The analyses were carried out on loose sand, dense sand, layered sand, reinforced sand bed.
