“…More recently, the study of the dynamic effects on buildings of the surrounding environment has became a challenging research topic, involving disparate expertise from the fields of physics, geology and engineering, and sometimes referred to as "urban seismology" (Diaz et al, 2017), (Green et al, 2016), (Ritter et al 2005). Moreover, the recent availability of low-cost measurement devices has encouraged the testing of large accelerometer networks for monitoring purposes (Barsocchi et al, 2018), (D'Alessandro et al, 2018), (Clementi et al, 2018), including through participative approaches as in (Matarazzo et al, 2018), where citizens were directly involved in monitoring the vibrations of bridges with their own smartphones (which are normally equipped with MEMS devices to measure accelerations).…”

The paper presents the results of an ambient vibration monitoring campaign conducted on so-called "Clock Tower" (Torre delle Ore), one the best known and most visited monuments in the historic centre of Lucca. The vibrations of the tower were continuously monitored from November 2017 to March 2018 using high-sensitivity instrumentation. In particular, four seismic stations provided by the Istituto Nazionale di Geofisica e Vulcanologia and two three-axial accelerometers developed by AGI S.r.l., spin-off of the Istituto Nazionale di Astrofisica, were installed on the tower. The measured vibration level was generally very low, since the structure lies in the middle of a limited traffic area. Nevertheless, the availability of two different types of highly sensitive and accurate instruments allowed the authors to follow the dynamic behaviour of the tower during the entire monitoring period and has moreover provided cross-validation of the results.

“…It can provide damage detection and characterization, risk assessment, or can be used to hypothesize future performance. Recently, the use of digital sensors has gradually replaced analog and/or mechanical devices in SHM systems; moreover, the advent of the IoT paradigm has brought interworking capabilities, opening to the use of sensor networks for the remote monitoring of monuments and/or structures of great impact [2]. Finally, information systems allow for processing the data produced by these sensors, whether they are images, vibration, acceleration data,…”

The historical buildings of a nation are the tangible signs of its history and culture. Their preservation deserves considerable attention, being of primary importance from a historical, cultural, and economic point of view. Having a scalable and reliable monitoring system plays an important role in the Structural Health Monitoring (SHM): therefore, this paper proposes an Internet of Things (IoT) architecture for a remote monitoring system that is able to integrate, through the Virtual Reality (VR) paradigm, the environmental and mechanical data acquired by a wireless sensor network set on three ancient buildings with the images and context information acquired by an Unmanned Aerial Vehicle (UAV). Moreover, the information provided by the UAV allows to promptly inspect the critical structural damage, such as the patterns of cracks in the structural components of the building being monitored. Our approach opens new scenarios to support SHM activities, because an operator can interact with real-time data retrieved from a Wireless Sensor Network (WSN) by means of the VR environment. INDEX TERMS Internet of Things, structural health monitoring, virtual reality, unmanned aerial vehicles, condition monitoring.

In order to study the deformation stability of rock slope during the excavation of cutting slope and ensure the safety of rock slope during construction and operation period, this article analyzed the deformation law of a typical slope excavation by monitoring the surface deformation and the internal displacement of the rock mass. The surface deformation of the slope is monitored by setting monitoring points, and the internal deformation of the slope is monitored by installing multipoint displacement meters and inclinometers. Therefore, the relationship between slope excavation and deformation is obtained. The analysis of monitoring results shows that the slope is stable before excavation, and the displacement of the slope is gradually increased with the slope excavation. After the excavation, the displacement of each slope tends to converge. The maximum displacement in surface monitoring points is 12.30 mm, and the displacement parallels to the direction of the expressway. The maximum vertical displacement in surface monitoring points is 10.60 mm which occurred in the third step; the maximum internal displacement is 11.02 mm which mainly occurs in the weak structural plane of the rock boundary. During the excavation of the weak rock slope, the slope rock mass is prone to large displacement deformation. After the excavation, the slope surface displacement and internal displacement tend to converge in a short time.
