Abstract

Intelligent health monitoring systems are becoming attractive topics in civil engineering because they not only ensure the safety of infrastructures; but also provide a method to research the evolving of damage and performance deterioration of infrastructures. However, its full implementation is very limited so far. Last year, two health monitoring systems were installed on two cable-stayed bridges for monitoring their health and assessing their safety in long-term service in mainland China, i.e. Shandong Binzhou Yellow River Highway Bridge and Harbin Songhua River Cable-stayed Bridge. The health monitoring system for Shandong Binzhou Yellow River Highway Bridge successively measures data and evaluates the safety on-line. The monitoring system for Harbin Songhua River Cable-stayed Bridge measures data periodically every year and evaluates the safety off-line. In this paper, two health monitoring systems for the above two cable-stayed bridges are introduced and partial data collected when the bridges subjected to vehicle loads and ambient condition during the static and dynamic tests are presented.
