Abstract

In order to overcome the insufficient bearing capacity of soil due to the special geological condition, the F-bent double decked bridge column, which carries both the north- and south-bound traffic loadings simultaneously, was used as a part of the extension system of the northern national highway No.1 in Taiwan. As the bridge column may be influenced increasingly by the heavy dead loading caused by the high bridge columns and the long-term eccentric effect, the F-bent double decked bridge system was carefully monitored and examined. Ambient vibration, static loading test, and dynamic truck loading test were carried out to verify the dynamic characteristic of the bridge system. For the purpose of long-term health monitoring on the new-constructed bridge, a finite element model was then establish, and the loading combinations executed in the in-situ experiment were analyzed numerically and compared with the collected data. The results have shown that the measured response of the bridge can be estimated reliably by the calibrated finite element model. By utilizing the deployed on-site health monitoring system and its corresponding numerical model, the safety of this special bridge can be protected.
