Abstract

The structural condition assessment of highway bridges is largely based on the visual observations described by the subjective indices, and it is necessary to develop a methodology for accurate and reliable condition assessment of in-service bridges. In this paper, an approach to condition assessment of in-service bridges making use of dynamic testing, in-situ monitoring and analytical and/or numerical simulations is proposed and applied to the instrumented Newmarket Viaduct, a 12-span bridge located in Auckland, New Zealand. Both ambient dynamic tests in two states and structural health monitoring data measured on the Newmarket Viaduct are reported and analysed. A finite element model of the bridge is successfully verified by using the natural frequencies and mode shapes extracted from the measured data. In the future work, realize meaningful interpretation of monitoring data is aim at inferring the state of a structure. Also, the FE models for structures calibrated and refined using the various types of field testing and monitoring or measurements data will be used in structural analysis simulations, yielding more realistic results.
