1. 1. Civil structural health monitoring : strategies, methods and applications

   Författare :Arvid Hejll; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

   Sammanfattning : This thesis describes a Civil Structural Health Monitoring (CSHM) method for assessment of civil structures by using a combination of advanced monitoring equipment with probabilistic based assessment. The numbers of civil structures such as bridges, tunnels, retaining walls, dams, etc. LÄS MER

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

   Författare :Cláudia Neves; Raid Karoumi; John Leander; Ignacio Gonzalez; Eleni Chatzi; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 3. Structural health monitoring using modern sensor technology : long-term monitoring of the New Årsta Railway Bridge

   Författare :Merit Enckell; Håkan Sundqvist; Daniele Inaudi; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Health Monitoring; bridges; sensory technology; fibre optics; concrete.; Building engineering; Byggnadsteknik;

   Sammanfattning : Structural Health Monitoring (SHM) is a helpful tool for engineers in order to control and verify the structural behaviour. SHM also guides the engineers and owners of structures in decision making concerning the maintenance, economy and safety of structures. LÄS MER

5. 4. Lessons Learned in Structural Health Monitoring of Bridges Using Advanced Sensor Technology

   Författare :Merit Enckell; Johan Silfwerbrand; Konrad Bergmeister; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Health Monitoring; Structural Health Monitoring System; bridges; sensor technology; emerging technology; fibre optics; fibre optic sensors concrete; creep; shrinkage; steel; distributed sensors; crack detection; Järnvägsgruppen - Infrastruktur; Järnvägsgruppen - Infrastruktur;

   Sammanfattning : Structural Health Monitoring (SHM) with emerging technologies like e.g. fibre optic sensors, lasers, radars, acoustic emission and Micro Electro Mechanical Systems (MEMS) made an entrance into the civil engineering field in last decades. Expansion of new technologies together with development in data communication benefited for rapid development. LÄS MER

7. 5. Timber-concrete hybrid structural systems : Examples, long and short-term dynamic monitoring, and numerical analysis

   Författare :Carl Larsson; Michael Dorn; Åsa Bolmsvik; Thomas K. Bader; Henrik Danielsson; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timber-Concrete Hybrid Structures; Timber Design; Structural Dynamics; Structural Health Monitoring; Byggteknik; Civil engineering;

   Sammanfattning : Timber-concrete hybrid buildings are an innovative solution to increase the amount of timber materials in modern buildings. Due to its lower impact on the environment than materials like steel and concrete, the demand for timber products is rising as the construction industry aims to decrease its environmental footprint.
