Footing comprises of the lower end of a column, pillar or wall which i enlarged with projecting courses so as to distribute load. Footings shall be designed to sustain the applied loads, moments and forces and the induced re… See more

Area required for footing Square = B = (w+w1)/P0 Where, Po = safe bearing capacity of soil w1 = self weight of footing w = self weight of footing For Rectangle = b/d = B/D A = b x d Net upward pressure on the footing q/p … See more

Bending Moment Critical section for maximum bending momentis taken at the face of the column For a square footing, Mxx = q x B/8 (L – a)2 Mxx = q x L/8 (B – b)2 Myy = q x B/8 (L – a)2 See more

To fix the depth of the footing shall be greater of the following: Depth from bending moment consideration d =√(M/Qb) where, Q = moment of required factor Depth from shear consideration Check for one way sh… See more
