Correlation between immediate settlement of rigid foundation and dimension ratio of rectangular footing on sand / Mazura Nor Zulkifli

The immediate settlement of footing on sand is governed by parameters such as contact pressure, dimension of footing and modulus of elasticity of the sand . It occurs immediately on application of the surface loads and is responsible for immediate settlement. The different ratios of L/B for a rectangular footing but with an equal area of contact are anticipated to give different values of immediate settlement. The sand is burdened with the same contact pressures through different dimension ratio of footing. Immediate settlement win be monitored and the result will show the effect of the different ratios of L/B with settlement for a specific load from the column. In this study an attempt is made to correlate ratios of footing shape of a rectangular foundation to settlement in sand .The settlement formula given by Terzaghi to calculate the immediate settlement of flexible footing and the formula of Skempton for rigid footings shall be used as the basis and guidelines in the study.
