| Abstract: | In this study, the behaviour of shallow foundations subjected to eccentric inclined loads is presented using nonlinear elastic finite element analysis. The material non-linearity of the soil has been taken into consideration by employing the hyperbolic stress-strain model. The formulation of an isoparametric interface/joint element which is used between footing base and soil media has been presented. Tests have been conducted to determine the characteristics of soil-footing interface. Forty cases of strip footing resting on sand and subjected to eccentric-inclined load which were studied by Agrawal (1986) through model tests, have been analysed. The predicted pressure-settlement, pressure-horizontal displacement and pressure-tilt characteristics have been compared with experimental results of Agrawal (1986) and a reasonable agreement between the two has been observed. |
