Abstract

The study aims to evaluate the effects of eccentricity, inclination of load along with eccentric-inclined load on performance of square footing resting over sand. The laboratory load tests were conducted on the model footing with eccentric load and/or inclined load. The eccentricity ratio (e/B) and inclination angle (α) varied from 0 to 0.2 and 0° to 30° respectively. The results shows that the bearing capacity decreases with increase in the load eccentricity and load inclination.

Abstract

The present paper examines the effect of soil structure interaction on a single bay, two-bay with symmetry and asymmetry multistory frames. The finite element analysis was carried out independently for the frame on the premise of fixed column bases in which members of the superstructure are discretized using the 2-node uniaxial beam elements. The model was analyzed separately for the soil base and foundation, by using the beam elements and plane elements to model the soil and foundation respectively.The foundation was used in the interaction analysis of the frame to quantify the effect of soil-structure interaction on the response of the superstructure. The response of superstructure was measured by the displacement at top of the frame and moments in the columns-beam joints. The effect of soil-structure interaction was found to be significant for two bay asymmetric structures. In this paper,the effect of interaction on the predicted settlements, forces and moments of two dimensional multi-bay frame structure was investigated. Interaction between soil and structure had been found to significantly affect the estimated structural forces and footing loads of different types frame structures.
