ABSTRACT
A web interface and data management system for dealing with Structural Health Monitoring (SHM) data was custom developed for the monitoring project of the Jaguari River Bridge in Brazil. The objective of the platform was to perform data collection and checking, as well as, allowing for the data visualization.
There are a few commercially available software solutions for the management and web visualization of monitoring data (Canary Systems 2015; Vista Engineering 2015; Monnit Corporation 2015; Datum Monitoring Services Limited 2015). However, most of these tools are intended for use with slower data rates (up to 1 Hz) and therefore, are not adequate for dealing with the data from live load monitoring. Due to this and to the factor that the group of researchers wanted to be able to process and visualize the data in specific ways, the choice to develop a custom system was made.
The tools for this system were developed using the Java language and it’s many available Application Programming Interfaces (API’s). A data management part of the toolset was developed with the purpose of downloading and processing the collected data and making it available for the web visualization tool (Figure 1).

This developed framework allowed for the full customization of the processing and visualization tools with a reasonable development time. The use of the Java language and the many available open-source API’s made for a reasonable development time. For SHM projects that involve a large amount of data, a web interface is an excellent option for allowing access to the collected data and analysis results. The web visualization tool is also specially useful for presenting the functionality of the monitoring system for the bridge owners and funding agencies.
