Thickness of plate required ( t ) : 6 x Ma / f x p
: 7.27 < 16 MM HENCE SAFE
CHECK FOR COMBINED TENSION AND SHEAR
Actual Tension + Actual ShearAllowable Tension Allowable Shear
(6 / 32.7)+(0.75 / 21.3) = 0.22 HENCE SAFE
CHECK FOR BOLT LENGTH
Bond Stress For M20 grade Cocrete : 1.20
Length of bolt required :: 6 *1000/(p* 20)*1.2: 115 mm HENCE SAFE
CHECK FOR BASE PLATE SIZE
Area of Base Plate (A) : 350x180 = 63000
: 0
Allowable pressure below the base plate : 5.0
Allowable pressure > Actual pressure HENCE SAFE
