Structural health monitoring (SHM) is an effective way to maintain the civil infrastructure against unexpected collapse. In recent years, many researchers have developed numerous damage detection methods to identify possible damage locations. The damage locating vector (DLV) method proposed by Bernal has received significant attention because this method was verified by a series of proof-of-con...

Structural damage identification approaches relying on structural vibration shapes (VSs) have been widely developed. Among the approaches, pseudo-force approach has attracted increasing attention during recent decade owing to fact that damage-induced is concentrated within region only and rapidly attenuates at undamaged locations. Transverse pseudo-forces (TPFs) flexural VSs used for identifica...

Preliminary notes This paper outlines the research aimed at developing an effective and reliable monitoring method for structural damage identification. A computational procedure for a direct iteration technique based on the non-linear perturbation theory is proposed to identify structural damage, when information about only natural frequencies for the damaged structure is required. The present...

The use of statistical methods for anomaly detection has become of interest to researchers in many subject areas. Structural health monitoring in particular has benefited from the versatility of statistical damage-detection techniques. We propose modeling structural vibration sensor output data using nonlinear time-series models. We demonstrate the improved performance of these models over curr...

Full recovery of coral reefs from tropical cyclone (TC) damage can take decades, making cyclones a major driver of habitat condition where they occur regularly. Since 1985, 44 TCs generated gale force winds (≥17 metres/second) within the Great Barrier Reef Marine Park (GBRMP). Of the hurricane strength TCs (≥H1-Saffir Simpson scale; ≥ category 3 Australian scale), TC Yasi (February, 2011) was t...

Post-earthquake structural safety is evaluated manually by certified construction inspectors and structural engineers. They inspect visible damage (e.g. cracks) on critical structural elements (e.g. concrete columns). This process is time-consuming and costly. In order to automate this type of visual inspection, several damage detection methods have been developed. However, most of them can onl...
