Design of Footing

In this article we will discuss the design of footing that is how footings are design because it is very important part of our building without good footing a building can't be good, without good footing building can fail at any time so it is very essential to have good fooding and to obtain good footing we must know the design of footing

                         Design of footings

Also footings are of various types searches stepped footing tapered footing circular footing rectangular footing except but in this article we are focusing on the design of the footing not on the types and classification of the footing hope you will enjoy this article so do like share and subscribe our YouTube channel for more information link given below

Design👇

Footings are designed for load over column and it's self weight,

 self weight of 

footing is taken as 10%. of column load.

p = load over column

Footing self wt. = 0.1×P

Total load on Footing = 1.1P

• Area of footing

Area of footing (Af) =

 Total land/SafeBearing capacity

Take safe Bearing capacity = 200kN/m2

if not given in ques.

Net Bearing Pressure in soil (q0)

This value should be considered for factored load over column.

q0 = 1.5𝑝/(𝐿×𝐵)
