In-situ test of pedestrian landscape bridge for benchmark SHM model towards smart city

The objective of this study is to establish a structural health monitoring (SHM) benchmark model for urban pedestrian bridges. It is generally recognised that urban pedestrian bridges are often considered as landscape and landmark structures. However, it should be noted that these bridges are more likely to be subjected to pedestrian loads than traditional vehicle loads. These demand a great deal of attention from the maintenance department. It is also useful to set up a monitoring benchmark model of the bridge to help manage traffic in this study, it is appropriate to propose a holistic strategy for the full-scale test of pedestrian landscape bridge. Study indicates that the case bridge operates within its elastic working state, with structural stiffness and strength meeting design and code requirements, demonstrating favourable dynamic performance. It can be concluded that the strategy employing water bags and pedestrians for testing yields satisfactory results. A bridge monitoring system will be considered, and when there is a significant increase in monitoring data, measures such as restricting pedestrian traffic and installing signage to guide local residents and traffic around the bridge will be considered, which plays an important role in the building of smart city.
