Uniform Loading over a
Small Circle of Radius ro, Remote from Edges |
Stress Under Load
Where:
Max. Foundation Pressure
Deflection:
Where:
W = Total load (force) (lbs)
v = Poisson’s ratio (assumed to be 0.3)
E = Modulus of Elasticity (lb/in2)
Do = Diameter where loading applied (in)
ro = Radius where loading applied (in)
k = Foundation of Modulus (lb/in2/in)
σa = stress, (lbs/in2)
qo = Maximum Foundation Pressure (lbs/in2)
ymax = Deflection (in)
