A LOW-COST PROCEDURE FOR QUICK MONITORING OF MONUMENTS AND BUILDINGS

摘要

A simple and reliable solution for structural monitoring of monuments and buildings, is presented. The system is based on the use of fixed instruments equipped with electric sensors and of a simple removable electric unit for periodical data acquisition. In this way the cost of the monitoring system can be greatly reduced without decreasing its reliability. In order to analyse the deformation behaviour of the structure, crack-gauges and long-base extensometers are generally installed as well as direct pendulums, clinometers and thermal-gauges. The flexibility of this monitoring system allows its use for the solution of any structural problem. Two examples are presented: the first one is referred to a long-term monitoring of a monument of great importance (the Church of SS. Giovanni and Paolo in Venice); the second one is a short-term monitoring during the strengthening works of a church and a bell-tower (the Church of Angone in the Camonica Valley).
