Behavior of square footing under eccentric loading on reinforced sand.

Civil Engineering

The lowermost part of the structure called as Foundation is the important part of the structure; function of foundation is to take loads of superstructure and transferred it to the soil. For the structural stability and to avoid settlement of structure bearing capacity of structure has a important role. We can improve Bearing capacity of soil by various techniques such as dewatering of soil, blending granular material, driving the sand piles & confining the soil. Here we are using geotextiles as reinforcing material, sand is reinforced with geotextiles, and reinforcing material is laid down at various depths along width of the tank. To check behavior of square footing under axial and eccentric loading on reinforced sand we have made one set up i.e. loading frame, tank of dimension 500x500x450 mm, proving ring , dial gauge, mechanical jack etc. behavior of square footing is check for axially and eccentric loading by this set up. Settlement of structure is calculated for axial and eccentric loading, and compared with the standard condition.
