  1. 1. 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 : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Health Monitoring; Machine Learning; Damage detection; Model-free based method; Artificial Neural Networks; Gaussian Process; Cost optimization; Civil and Architectural Engineering; Byggvetenskap;

    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

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

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

    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.
