Monitoring building structures ultrasonically

A new ultrasonic system for the inspection of building structures has been developed.
Monitoring building structures ultrasonically
Technologies that predict the severity status of degradation in a building structure that are currently on the market often times fall short. This is because some of them can only be applied in laboratory situations. Additionally others provide only inherent features such as average parameter values or they are very expensive.

A new technology using an ultrasonic system is found on analysis of the generation of elastic waves in heterogeneous materials. The system contains proprietary probes or sensors, automatic data acquisition software, a signal processing expert system and a database for storage of inspection information.

The technology provides vertical and horizontal section images (via 3D mapping) of the stress concentration within the building structure. This is important because it points out weak points which can be dangerous to the integrity of the structure in terms of future load conditions. It analyses the ability of building structures to remain stable during present and future loads as well as the degradation velocity of building foundation. This can all be attained at a minimal cost.

The new system can be especially useful for specialists in civil/building engineering, for building maintenance companies and producers of pre-fabricated ferro-concrete structures and parts. Financial resources and joint venture for further development, manufacturing and marketing of the system are sought.
