   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural health monitoring; Traffic monitoring; Bridge monitoring; Bridge Weigh-In-Motion; BWIM; Damage detection; Suspension bridge bearings; Axle loads; Dynamics; Temperature effect;

   Abstract : The field of bridge monitoring is one of rapid development. Advances in sensor technologies, in data communication and processing algorithms all affect the possibilities of Structural Monitoring in Bridges. READ MORE

5. 3. Continuous Preventive Bridge Maintenance : Effect of High Pressure Washing on Concrete Bridges

   Author : Louise Andersson; Johan Silfwerbrand; Anders Selander; Ylva Edwards; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge maintenance; preventive maintenance; chloride ingress; high-pressure washing; Concrete Structures; Betongbyggnad;

   Abstract : In Sweden, as in many other countries, preventive maintenance of structures andbridges is considered important. It provides several benefits such as prolonged lifespan or service life, less need for repair, and hopefully reduced costs and lowerenvironmental impact.A large part of Sweden’s bridge stock is getting quite old.

6. 4. Structural Health Monitoring of Bridges : Model-free damage detection method using Machine Learning

   Author : Cláudia Neves; Raid Karoumi; John Leander; Ignacio Gonzalez; Eleni Chatzi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Health Monitoring; Machine Learning; Damage detection; Model-free based method; Artificial Neural Networks; Gaussian Process; Cost optimization; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : This is probably the most appropriate time for the development of robust and reliable structural damage detection systems as aging civil engineering structures, such as bridges, are being used past their life expectancy and beyond their original design loads. Often, when a significant damage to the structure is discovered, the deterioration has already progressed far and required repair is substantial. READ MORE

7. 5. Structural Health Monitoring of Bridges : Data-based damage detection method using Machine Learning

   Author : Ana C. Neves; Raid Karoumi; Elsa Caetano; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Health Monitoring; damage detection; Machine Learning; data-based methods; Artificial Neural Networks; Value of Information; Structural Engineering and Bridges; Bro- och stålbyggnad;

   Abstract : Civil engineering structures built according to modern codes are designed for a service life of normally more than 100 years. At the same time, there is a growing pressure to keep existing aged structures in service despite the fact that they have reached the original designed lifetime, with bridges being a good example of this.
