Abstract

The InfraWatch project is a Dutch research project, aimed at developing novel techniques for large-scale monitoring of concrete infra-structures. The project involves a large bridge, fitted with multiple types of sensors that capture the high-resolution dynamic behavior of the bridge. With 145 sensors measuring at 100 Hz, a huge amount of data becomes available that describes various aspects of the bridge’s response to traffic and weather conditions, both long and short-term. A single truck passing the bridge already encompasses almost 50,000 readings, such that detailed modal analysis can be performed. At the same time, this data-intensive monitoring continues around the clock, as well as the calendar, such that more gradual effects like changes in temperature and traffic conditions can be tracked as well. This wealth of information is being analyzed in various ways − which will be elaborated in this paper − combining both computer science and civil engineering expertise. The InfraWatch project is a central project in the Dutch national research program “Integral Solutions for Sustainable Construction (IS2C)”, which is aimed at developing novel techniques for a next generation predictive simulation model for service life assessment. Other projects within this program are concerned with key degradation processes in structural concrete, such as ASR and chloride penetration. In the near future, the progress of such degradation processes will be measured by dedicated sensors, to be developed within these ‘sister projects’. Such direct degradation measurements will complement the indirect measurements currently performed, which essentially only monitor the dynamic load on the bridge. A lab experiment is currently being developed in the Stevin II laboratory of Delft University of Technology, where ASR and chloride penetration will be measured alongside with the dynamic deformations of a test beam under load while focusing on the mutual interaction of both the materials degradation processes and the structural response.
