The University of Sharjah in Dubai has developed and patented a device to protect buildings from earthquakes, capable of reducing vibrations by up to 75% through the use of granular materials such as sand.

The development, which was called “Particle-based energy dissipation device”, is based on the natural physical properties of sand. Steel containers are filled with sand or other granules, which, moving and compressing under the influence of vibrations, dissipate their energy. According to the results of experiments, the damping coefficient of the device varies from 37% to 75%, which is superior to many traditional passive protection systems.

The design of the device is versatile. The containers can be of various shapes and sizes, such as rectangular or cuboid, and have multiple steel plates to improve efficiency. This allows the system to adapt to any architectural features of the building, and additional plates provide the ability to work under high loads.

Cost-effectiveness and simplicity are key advantages of the new technology. According to Professor Moussa Leblouba, the device is easily manufactured from standard building materials available in any store. This makes it ideal for both new buildings and the modernization of existing structures in earthquake-prone regions.

The device's application goes beyond earthquake protection. It is also effective in reducing vibrations caused by wind or traffic, making it useful in different climate zones and urban settings. Professor Mustafa Zahri stressed that this technology is especially important for regions with limited financial resources, where the implementation of expensive systems is not affordable.

The patent, issued in the US, opens up the prospect of international collaboration for the inventors. It is planned to involve engineering companies, municipalities and emergency organizations to integrate this technology in different countries.
