REVIEW STUDY OF VARIOUS SHAPED ISOLATED FOOTING UNDER MONOTONIC AND INCREMENTAL CYCLIC LOADING ON B. C. SOIL

Bearing capacity and settlement are the two major criteria for design of foundation. Also it is not always subjected to monotonic loading but it is also subjected to cyclic loading. The examples are lifts, bridges foundation, machine foundation, offshore structure, wind waves to structure etc. The load transmitted to the soil causes the settlement of soil. The method of foundation design requires that they must possess sufficient safety against failure and settlement must be kept within the tolerable limits. These requirements are dependent on the bearing capacity and compressibility of soil. It is considered that the settlement criterion is more critical than the bearing capacity in the designs of shallow foundations. The load settlement behavior of footings of rectangular, circular and square shapes is well known. In the present study a review study has been done for the comparison between various soil test results and load-settlement behavior of rectangular, octagonal, hexagonal, square, triangular and circular footing under monotonic and incremental cyclic loading.
