What is the formula of allowable bearing capacity?

• qu/qall

• qu/Fs

• qu/Qall

• qu= BL

Following are the natural bearing capacity failure except:

• General shear failure

• Local shear failure

• Tensile shear failure

What is the Terzaghi formula under circular foundation?

• qu = 1.3 c'Nc + qNq + 0.5 YBNy

• qu = 1.3 c'Nc + qNq + 0.3 YBNy

• qu = 1.3 c'Nc + qNq + 0.2 YBNy

• qu = 1.3 c'Nc + qNq + 0.4 YBNy

Following are the important note to be highlight for B & L except:

• Wide strip foundation, L is greater than B

• Square foundation, B=L

• Square foundation, B>L

• Circular foundation, B=L= diameter
