Explain the Modification Factors for Inclined Foundation Base.

calculate the stress increase at 4 meters below the center of a 2 meter2 foundation imposing 293 KPa. Use the 60 degree approximation method.

A structural engineer wants to consider placing the base of the building so deep that the soil below will not experience any additional load. They asked you to design a fully compensated mat foundation under the entire building. They has determine that the plan view of the building will be 65 ft by 65 feet. and the building will weighs 10,790 kips. The clayey soil beneath the site has a cohesion of 418 psf and the unit weight of the soil is 118 pcf. How deep will they have to place the structure to fully compensate for the weight of the building.

Find the change in vertical stress at level 3m below the base of footing at Point A. It is to be assumed the thickness of both footings are the same. L1 = 2.5m L2 = 1.5m L3 = 4m L4 = 6m L5 = 7m
