Design Calculations

Footing Size Calculations

Gross Soil Bearing Capacity = 196.00kN/m^2

Reduction of force due to buoyancy = 0.000kN

Area from initial length and width, Ao = Lo X Wo = 280.000sq m

Min. area required from bearing pressure, Amin = P / qmax = 105.858sq m

Note: Amin is an initial estimation. P = Critical Factored Axial Load(without self weight/buoyancy/soil).

Final footing dimensions are:

qmax = Respective Factored Bearing Capacity.

Length of footing, L : 35.000m

Width of footing, W : 7.950m

Depth of footing, Do : 0.600m

Area, A : 278.250sq m

Length of left overhang, Lleft_overhang : 2.500m
