Low frequency sensitive tiltmeters for dynamic structural status evaluation of hystorical monuments

Barone Fabrizio, Giordano Gerardo

Abstract

The dynamic structural analysis of historical monuments for health evaluation and long term preservation requires a long term acquisition of linear and angular displacements, mainly in the low frequency region (<< 1Hz), that has to face to many technical problems spanning from the problem of uncoupling displacements from tilts, to cost and size of instrumentation. To overcome this problem, we developed an innovative small and light linear and angular sensor, based on the Folded Pendulum Model, perfectly suitable for a permanent non-invasive low-power monitoring of historical monuments. In this paper, after a description of the tiltmeter model and performances, we focus the attention to its application to historical monuments monitoring.
