Vibration Testing of a Bell Tower

The measurements and analysis presented here are performed by Dr. Reto Cantieni, RCI Dynamics, Switzerland.

This case consider measurements conducted on the bell tower of the St. Peter & Paul church in Zürich, Switzerland. The measurements were conducted using a LMS Pimento data acquisition system. The sensors were PCB 93B31 accelerometers. Modal analysis was prepared with ARTeMIS Testor and conducted with ARTeMIS Extractor Pro using Crystal Clear SSI.
