In this work, we present and discuss on the deflection estimation of a bi-dimensional panel by using Fiber Bragg Gratings (FBGs) as strain sensors embedded in the structure and a method based on the classical beam theory. The existing difficulties in the direct measure of the deflection are overcome thanks to the proposed technique and a real-time indirect structural monitoring is possible both on small and large structure. In many tests the estimated deflection with the proposed method has been compared with direct deflection measurements obtained with a mechanical comparator showing good agreement. A resolution of few tens of microns over a surface of the order of 1 m2 has been reached.

Wireless sensor networks can be beneficial for monitoring ambient vibrations in historical buildings where the installation of traditionally wired system may be either difficult due to wiring difficulties or forbidden due to prohibitive legislation. In this paper, a novel wireless sensor network architecture is presented that is focusing on efficiently monitoring ambient vibrations in historical buildings. Traditional wired monitoring technologies are often difficult to be installed in historical buildings either to high costs for installing the wires or to prohibitive legislations. Employing a wireless system could be beneficial. However, as there is no wireless system of high resolution available in the market, an innovative network architecture is proposed that efficiently combines the benefits of both the wired and wireless systems. The problem of synchronization that this novel architecture introduces, is also discussed in this paper along with a possible solution.

Great Belt

<p>The monitoring system on the Great Belt Bridge has been under a renewal process for the last 4 years. <p>Worn down sensors for alarm and maintenance purposes have been replaced by new more appropriate sensors. <p>A new structural health monitoring system for maintenance with a database and a graphical user interface (GUI) has been developed. The software collects and stores measurement data from a large number of sensors on both the cable‐suspended East Bridge and the low‐level West Bridge. From summer 2018 more than 400 sensors can be monitored from one GUI. More sensors are following in 2019. <p>The project has been carried out by Rambøll as client consultant and Krabbenhøft & Ingolfsson as main contractor.
