Dealing with the unreadability of monitoring data poses a significant challenge in bridge structural health monitoring (SHM). This paper proposes a digital visualization approach of monitoring information based on building information modelling (BIM), which consists of establishing of the bridge information model (BRIM) and the dynamic visualization techniques. Multi-scale finite element models (FEMs) serve as the critical point for investigating the hidden information of the monitored data with the aid of big-data methods. Then the life-circle information is saved in the BRIM to realize information integration, which includes the structural designing data, operation data, monitoring system, load and environmental condition, damage information, FEM analysis results, etc. A customized four-dimensional (4D) visualization platform is subsequently developed via a secondary development interface to present heterogeneous information, reflecting the long-term state changes of infrastructures. Finally, the proposed digital visualization approach is applied to a three-span continuous model bridge case for verification.
