Abstract [sv]

Bridges with critical roles in heavily loaded transport infrastructures often need to be kept in service despiteknown damage and deficiencies. Closing or limiting the traffic on a bridge, leading to traffic diversions, issometimes not a feasible option. The current paper describes an approach for securing the functionalityand the safety of critical bridges by using an innovative smart system for monitoring and conditionassessment. It builds on the use of wireless sensor networks, advanced assessment methods, and cloudbased services for storage and distribution of results. This is an ongoing research project and the progressso far is presented in this paper. A case study of the Old Lidingö Bridge in Stockholm, Sweden, is used todemonstrate the approach. The monitoring system installed, devices for energy harvesting, and methodsfor condition assessment are presented. Some preliminary results on the condition of the bridge are alsopresented.
