Abstract

Being the first bridge with a main span exceeding 1 km in Chinese mainland, the suspension Jiangyin Bridge had been instrumented with a structural health monitoring (SHM) system when it was completed in 1999. After operation of several years, it was confronted with problems of malfunction in sensors and data acquisition units, and insufficient sensors to provide necessary information for structural health evaluation. The SHM system has been upgraded by a consortium of The Hong Kong Polytechnic University and Jiangsu Transportation Research Institute. Structural health monitoring data have been continuously collected since then. Making use of the long-term monitoring data, the performance assessment is carried out for the bridge by means of multi-dimensional data analysis. This paper reports the performance assessment with emphasis on: (i) analysis of temperature profile and effects; (ii) recognition of wind characteristics and effects; and (iii) characterization of structural dynamic properties.
