Slender Structures
Slender structures, such as telecommunication towers, chimneys and elevated water reservoirs etc. can be very sensitive to dynamic wind loading. Indeed, wind-induced forces can cause significant dynamic response which may lead to structural damages. In the case of telecommunication towers, it can also lead to signal transmission distortion.
Therefore, design criteria for slender structures must include dynamic stiffness which depends on the main resonance frequencies and inherent structural damping. These characteristics must be measured when the structure is first erected and compared with the design data. It is also recommended that they are measured during maintenance activities.
In addition, in harsh/windy environments, the permanent monitoring of structural vibrations is recommended. Indeed, the natural frequencies of a structure can be obtained from acceleration measurements and the shifts of these natural frequencies values can be a good criterion for the evaluation of the structure’s integrity, allowing for preventive action.

Application with Cloud Monitoring
Permanent monitoring for Telecommunication Tower
Structural Health Sensors and inclinometers have been used in combination with a Recovib.Monitor acquisition system and the Recovib.io platform for the permanent monitoring of telecommunication towers. The Structural Health Sensors are well suited for these outdoor applications because of their -40°C lower operational temperature limit and their inherent lightning protection. They are also insensitive to the high radiation environment due to the presence of the telecommunication antennas. The system is equipped with 4G connectivity.
Used Solution
SHS (Structural Health Sensor) and DAI (Dual Axis Inclinometer) with Monitor data acquisition system.
All the collected data managed by Recovib.io Cloud Platform.
