“…Extensive use of long term continuous monitoring is quite new, enabled by recent advances in data acquisition, processing and management. Long term monitoring of the structural response was pioneered in China and Japan (Abe and Amano 1998, Wong et al 2000, Ko and Ni 2005: nowadays, several bridges are instrumented in Europe (Casciati 2003), United States (Pines and Aktan 2002), Canada (Mufti 2001), Korea and other countries. Recent developments consist in formulating a general framework of asset management in a life-cycle perspective (Messervey and Frangopol 2008).…”

Dependability of a structural system is a comprehensive concept that by definition describes the quality of the system as its ability to perform as expected in a way that can justifiably be trusted. One of the attributes of dependability is integrity, which can be interpreted as the absence of improper alterations of the structural configuration. The assessment of the integrity during the whole life-cycle can be carried out efficiently by implementing a monitoring system able to detect and diagnose any fault at its onset. The essential feature of the monitoring system dealt with in the paper is the elaboration of data gathered on site by a combination of simulation and heuristics. In detail, the first part of the paper deals with the extension of the concept of dependability, as formulated in computer science, to structural engineering. The second part illustrates a two-step hierarchical strategy for the assessment of the integrity of a structure through monitoring of its response under ambient vibrations; Bayesian neural network models are used for fault detection and diagnosis from observable symptoms. In the first step, the occurrence of any fault is detected and the relevant portion of the structure identified; in the second step the specific element affected by the fault is recognised and the intensity of the alteration of the structural performance evaluated. The strategy is applied to assess the integrity of a long-span suspension bridge subjected to wind action and traffic loading. As the bridge is under design, measured data are simulated by analysing the response of a detailed FE model of the whole structural system. The final objective of the study is the optimal design of the integrity monitoring system for the bridge. © 2011 Taylor & Francis

“…The bridges are designed to withstand up to a one-minute mean wind speed of 95 meters per second. A sophisticated bridge monitoring system called ''Wind and Structural Health Monitoring System (WASHMS)'' (Lau and Wong 1997;Lau et al 1999;Wong et al 2000) has been installed on these three long-span cable-supported bridges to monitor the integrity, durability, and performance of the bridges. The WASHMS consists of approximately 800 specialized sensors and their associated sensor interfacing units mounted at strategic locations on the bridges (Wong et al 2001a).…”

“…Structural health monitoring [1][2][3][4] , known as the most ideal method for evaluating the structural state, can detect the damages occurred on structure in time, avoiding the sudden structural failure and cutting down the enormous maintenance expense. In recent years, people pay more attention on real time structure health monitoring of bridges because of sequent bridge collapse accidents happened all over the world.…”

Structural health monitoring is thought to be a promising way to monitor and evaluate the health state of bridges. Crack identification is one of the most important aspects in structural health monitoring, because the collapses of concrete bridges are mostly due to occurrence and propagation of initial cracks. In this paper, metal wire has been adopted to form a regular crack detecting network on concrete structures. The method along with the related system has the ability to real time monitor the occurrence, propagation, length and location of initial crack on the surface of concrete structures.
