Behaviour of Surface Strip Footing on Soft Soil Subjected to Eccentrical and Inclined Load

Kanhar, Debasish (2017) Behaviour of Surface Strip Footing on Soft Soil Subjected to Eccentrical and Inclined Load. MTech thesis.



The soil around foundation plays a very critical role during its performance. The strip foundation is one in which inclined or eccentric loads surrounds soil mass beneath footing. The strip form an enclosure in which soil is confined and works as a unit with the overlain foundation to transfer superstructure load to essentially at the level of strip resulting increase in the ultimate bearing capacity of the structure. This present works is an attempt to behavior of strip footing subjected to an eccentric and inclined load on soft soil. The failure mechanism of strip footing located above the soils is studied analytically. The present work focused on the analysis of strip footing subjected to inclined and eccentric load using finite element software PLAXIS 2D.
The various parameter considered for the study were inclined load, eccentric load, inclination angle, width of strip footing(B), depth of footing in terms of height(H), the ratio of eccentricity from applied to the width of footing(e/B), plasticity index of soft soil. Figures involving the load carrying capacity with affecting factors presented. The result indicates the strip foundation had significant effect in improving the ultimate bearing capacity with different plasticity index. The depth of footing does not show any improvement in ultimate bearing capacity.
