Abstract
The Clifton Suspension Bridge is an emblematic structure in Bristol, UK. In this paper, a rapid deployment of a structural health monitoring (SHM) system for short-term monitoring is described. The system, deployed in a single day, integrates wireless SHM and open-source data management systems to gather valuable information about the bridge use (loading). The deployed system can be used to inform structural response models as well as studies for traffic engineering purposes. The use of open-source software was critical to the successful deployment.
Highlights
The maintenance of ageing civil infrastructure is a concern the world over, such as in the UK, where an ‘asset time bomb’ has been described (Thurlby, 2013; Thurlby and Rimmel, 2015)
This paper reports on the rapid deployment of a wireless sensor network (WSN) on the Clifton Suspension Bridge (CSB) in Bristol in the UK
Another technology much less discussed in the field of structural health monitoring (SHM) is the use of application interfaces (APIs) and open-source software (OSS) for data management
Summary
The maintenance of ageing civil infrastructure is a concern the world over, such as in the UK, where an ‘asset time bomb’ has been described (Thurlby, 2013; Thurlby and Rimmel, 2015). SHM using WSNs for bridge structures has been the subject of much recent research (Hoult et al, 2008, 2009, 2010; Lynch et al, 2006; Rodenas-Herráiz et al, 2016; Stajano et al, 2010; Webb et al, 2014), with a number of large-scale deployments Jang et al, 2010, 2011; Kurata et al, 2013; Lynch et al, 2006) Another technology much less discussed in the field of SHM is the use of application interfaces (APIs) and open-source software (OSS) for data management. ■ attempt a rapid SHM deployment for short-term monitoring; ■ integrate wireless SHM and open-source data management systems; ■ use existing monitoring systems to gather information about bridge use to inform structural models; and ■ correlate structural data and traffic management data to explore the use of structural sensors for monitoring bridge use
