Abstract: The construction of high voltage electrical network in Egypt requires the construction of thousands of lattice towers of different shapes and sizes. Generally, the foundations of such towers are subjected to three types of loads, the downward trust (compression), the pullout (tension) and the side trust (horizontal shear). The soil above and surrounding a tower foundation has to resist a considerable amount of tension force and lateral force. In the current research, the effect of different parameters, such as the soil type, footing dimension, relative compaction and the ratio between the foundation depth to footing width on the pullout capacity of shallow horizontal footings subjected to uplift force and lateral force were studied. A detailed series of laboratory tests were carried out considering the footing dimensions (3.5*7 cm, 5*10 cm and 7.5*15 cm), the relative dentists (100% and 92%) were used. The ratio between foundation depths to footing width is (1, 1.5 and 2.5). A detailed series of laboratory tests were carried out to expect the behavior of the footing of electrical towers. A parametric study is performed to investigate the load displacement curve and the ultimate pullout load of shallow footings under tension force and lateral force.
