Abstract

Monitoring of the in-field performance of bridges and other structures has become a very valuable tool to the Iowa DOT Office of Bridges and Structures. There simply is no better way to understand how structures react to loadings than by physical monitoring and testing. There are a large number of monitoring tools that are commercially available. One such tool is manufactured by an Iowa- based company known as SENSR. The SENSR hardware consists of tri-axial accelerometers, tiltmeters and temperature sensors. The unique nature of the SENSR hardware is that it is easily deployable by personnel with only a limited amount of training. To evaluate the SENSR system, the Bridge Engineering Center completed two tasks. First, the SENSR system was installed on a laboratory specimen adjacent to sensors with known performance characteristics to validate the accuracy of the SENSR system. Second, the SENSR system was field installed to understand how to install and utilize collected field data.
