Digital Twin Aided Vulnerability Assessment and Risk-Based Maintenance Planning of Bridge Infrastructures Exposed to Extreme Conditions

Over the past centuries, millions of bridge infrastructures have been constructed globally. Many those bridges are ageing and exhibit significant potential risks. Frequent risk-based inspection maintenance management highway is particularly essential for public safety. At present, most rely on manual methods management. The efficiency extremely low, causing risk deterioration defects to increase day by day, reducing load-bearing capacity bridges, restricting normal safe use them. applications digital twins in construction industry gained momentum has gradually entered information age. In order obtain share relevant information, engineers decision makers adopted over entire life cycle a project, but their still limited data sharing visualization. This study further demonstrated unprecedented sustainability vulnerability assessments, which can enable next generation framework. adopts obtained from constructor Zhongcheng Village Bridge Zhejiang Province, China as case study. model establishment, collection sharing, processing, planning highlighted. Then, integration “digital (or Building Information Modelling, BIM) + model” established, will become more effective platform all stakeholders mitigate risks uncertainties exposure extreme weather conditions cycle.
