How we decide the type of footing?

Answer

you can select the footing type according to the soil type, shear strength, bearing capacity of soil and the distance of the hard strata below the soil, soil profile and bearing capacity difference in various points of the plot.

Question { 2979 }

How we decide the depth and size of footing? Give a example?

Answer

you can find out the depth of the foundation using rankines formula, mostly provide upto the hard strata (for skin friction piles the depth of pile will be calculated by giving importance to the friction it developes). the size of the foundation will be decided by the safe bearing capacity of the soil.
for example if the safe bearing capacity of the soil is 225 kn/m2, and the load is 15 kn means provide 225/15= 15 m2 of footing.

What is mean by uniaxial bending

Answer

since the column may be loaded in uniaxial( one axis) or biaxial( two axis) , the possiblity is when only the beam in x direction or y direction is rested on column, only towards one axis of the column(x or y) the bending moment will develop. it is called uniaxial bending.
