Bearing Capacity of Circular Foundation on Sand Layer of Limited Thickness Underlain by Rigid Rough Base Subjected to Eccentrically Inclined Load

CODEN: GTJODJ

Abstract

Laboratory model test results for the ultimate bearing capacity of a shallow rough circular surface foundation over a sand layer of limited thickness underlain by a rigid rough base subjected to an eccentrically inclined load have been presented. The sand layer for tests was prepared at a relative density (Dr) of 69 % using five different thicknesses, H. Tests were conducted at H/B values of 0.3, 0.5, 1, 2, and 3 (B = diameter of foundation). The load eccentricity ratio e/B varied from 0 to 0.15, and the load inclination with the vertical (α) was changed from 0° to 20° in 5° increment. Based on the model test result, a reduction factor has been proposed that can be used to estimate the ultimate eccentrically inclined load per unit area of the foundation supported by a sand layer of limited thickness, from the ultimate bearing capacity of a foundation on a sand layer extending to a great depth under an eccentrically inclined load.
