Experimental Verification of the Static Method for Seismic Design of Vibration-Isolated HVAC Equipment

Motivated by the repeated damage to vibration-isolated equipment in almost all strong earthquakes that occurred in the past four decades, an experimental study was conducted to verify the adequacy of the current static method used for the seismic design of this type of nonstructural components. The study included earthquake-simulator tests of two HVAC equipment items supported by restrained vibration-isolators. The test results confirmed that …
