Design of the Base


Assume Material for the base : Cast Iron ASTM Class 40


1.    Bearing Pressure between the nut and the Base









2.    Buckling Analysis of the Base:








Check for Johnsonís Column:





If it is a Johnsonís Column then find the Critical Load by using equation and check whether Buckling occurs or not:




3.    Compression Stress on the Column:


















4.    Checking Stresses on the Base Seat:




Assuming a uniformly distributed load on the entire base seat at a circumference which is in the center of the base seat







5.    Bearing Pressure between the Base and Concrete Surface:
