Abstract

This work reports a case study of a structural health monitoring (SHM) system combining large and micro scale measurements installed in a 16th Century Church in Aveiro. This dual scale SHM system relies on a network of 24 fibre Bragg grating (FBG) sensors to perform micro scale, high resolution displacement and temperature measurements in several key points of the structure, while the large scale measurements are ensured by a scanning laser range finder. The results demonstrate that the developed systems allow adequate monitoring of the evolution of deformation in buildings, in different scales, keeping the visual impact in the structure reduced to a minimum and contributing for the implementation of best practices for rehabilitation of historic and cultural heritage.
