Behaviour of Skirted Strip Footing Subjected to Lateral Load
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
The knowledge of performance of skirted strip footing on slope subjected to lateral load may be useful for industrial machines foundation, footing of retaining walls, bridge abutment on steep river slope and portal framed buildings are not only subjected to vertical or inclined loads but also to moments. Moments on the foundation base are mainly caused by lateral forces acting on the structure. Sometimes footings may be placed on slopes due to the unavailability of land, so it is necessary to use the land on slope for various construction works and architectural needs. Hence, it necessitates to understand the performance of skirted strip footing on slopes subjected to lateral loading conditions. In the present work, static lateral load tests were performed to study the performance of equal and unequal skirted strip footings. This is an extensive program of work, done on equal skirted strip footing having depth to the width of footing ratio (d/B) equal to 0.0, 0.25, 0.5, 1.0 which is published earlier. In this paper, for equal skirted strip footing two depth to the width of footing ratio (d/B) such as 1.5 and 2.0 is an additional work. So in this paper different parameters studied were effect of the ratio of depth of skirt to width of footing, the ratio of distance of footing from crest to the width of footing. Tests were performed for unequal skirted strip footing with longer skirt at the load edge and rear edge, to know the better placement location for longer skirt in unequal type of footing. From the result of experimental work, it was found that as the depth of skirt increases and as the distance of the crest to the width of footing increases, the ultimate lateral load carrying capacity of footing increases significantly.
