🧱 ASHRAE Ch 49 (Concrete Mass Ratio 2:1, Spring Isolator Static Deflection 1"-2")

Floating Concrete Inertia Base Calculator

Size structural steel pour-form concrete inertia bases and open-spring vibration isolators for large reciprocating compressors and end-suction centrifugal pumps under ASHRAE Chapter 49: calculate concrete foundation inertia mass (maintaining 2:1 concrete-to-equipment weight ratio), calculate spring static deflection (1.0" to 2.0" to achieve >95% vibration isolation efficiency), and piping profits.
