(1888PressRelease) July 17, 2015 - Bristol, UK : Imetrum's non-contact video measurement extensometer has been used in an interesting study looking at the dynamic response of reinforced concrete (RC) flat slabs after a sudden column loss. The study, published recently in the academic journal Engineering Structures, was carried out to provide much needed experimental evidence regarding the distribution of forces and damage patterns after an extreme event to provide an indication of potential collapse of a structure.

The experiments involved testing the RC slabs under static load increases or dynamic column removal and the reaction forces and deflections were recorded throughout. Imetrum's Dynamic Monitoring Station was used to capture the dynamic motion during the tests. The system comprised a controller with the sophisticated Video Gauge™ software installed, together with a high-speed camera that was used to capture the behaviour of the slabs after column removal. The images were recorded at 2500fps and then processed by the sophisticated Video Gauge™ software to obtain deflection readings and to estimate column removal time. One of the best benefits of the Imetrum system is that fact that because it is video based, it enables key events to be captured as a simple visual record but also the video can be replayed for re-analysis of additional data points offline. This is particularly important in this instance where the slabs are tested to destruction.

Speaking from Imetrum's headquarters in Bristol UK, Paul Waterfall, Product Manager says, "Our non-contact video measurement systems are extremely versatile and can be used in the laboratory for academic research into structural dynamics such as this as well as "in the field", where they are operate in a variety of scenarios including monitoring bridges and railway tracks even investigating potential damage to an historic bell tower from the pealing bells."

Imetrum's product now has over 300 users worldwide and is a versatile, non-contact video based system that allows the user to test a variety of important parameters (strain, rotation, displacement etc.) in real time, in a single test. As the Imetrum system is video based, a record of the test can be saved so engineers can either post process the test or complete further analysis without the need for repeating the test, saving both time and money.
