Earthquakes induce damaging ground vibration characterised by low frequency content and high displacements. Products intended for use in earthquake prone areas must therefore be designed to ensure they can withstand earthquake-induced vibration. However, as the vibration induced by earthquakes is highly complex, the resilience of a product to earthquake vibration cannot be determined with great confidence by modelling alone. Therefore, physical testing remains the only reliable method of verifying the performance of products under earthquake conditions.
However, for numerous reasons, the conduct of earthquake vibration testing is not easy and few test houses are able to carry out such testing in a credible way. Drawing upon decades of experience in vibration testing in other challenging areas such as naval and aerospace domains, our engineers have been heavily engaged in developing solutions for seismic vibration testing over the last 12 months. As a result of these efforts, Austest Laboratories is pleased to announce significant expansions in this area and the new capability to conduct earthquake vibration testing of equipment and other products.
