There is no simple formula for reciprocating equipment foundations.
Typically you apply a list of general "go-by" sizing criteria and then
check your trial sizing using dynamic procedures which includes 6 degree of
freedom springs. The general "go-by's" include items such as foundation
mass should be three to five times the mass of the machine, minimum
foundation thickness should be greater than one fifth the least dimension
or one tenth the largest dimension, the center of gravity of the machine
plus equipment should be within 5 percent of the foundation center of
There are several references such as "Design of Structures and Foundations
for Vibrating Machines" by Suresh Arya, Michael O'Neill, and George Pincus.
Most good foundation engineering books cover the subject.

Has any one a simple formla to design concrete foundation under
reciprocating equipment with higher accurecy and less design time
