  1. 1. Mapping of Dependent Structural Responses on a Prestressed Concrete Bridge using Machine Learning Regression Analysis and Historical Data : A Comparison of Different Non-linear Regression Approaches

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Vedad Coric; [2023]
    Keywords : Prestressed Concrete Bridges; Structural health Monitoring; Machine Learning; Regression analysis; Infrastructure management;

    Abstract : Prestressed concrete bridges are susceptible to deterioration over time which might significantly affect their capacity and overall performance. In previous decades, infrastructure owners have found that continuous monitoring of these assets is a valuable tool for their management as it facilitates the decision-making process regarding the intervention strategies required.

  4. 3. Application of Lamb waves using piezoelectric technique for structure health monitoring

    University essay from KTH/Hälsoinformatik och logistik

    Author : Simon Mauritz; [2023]
    Keywords : Structural health monitoring SHM ; damage detection; Lamb waves; piezoelectric PZT ; printed circuit board PCB ; circuit simulation; Strukturell hälsoövervakning SHM ; skadedetektering; Lambvågor; piezoelektrisk PZT ; printed circuit board PCB ; kretssimulering;

    Abstract : Structural health monitoring (SHM) is damage detection strategy for aerospace, civiland mechanical infrastructure. This project tries to show that Lamb waves, that are being generated and sensed with piezoelectric transducers, can be used for damage detection in a SHM system. READ MORE

  5. 4. U - Net Based Crack Detection in Road and Railroad Tunnels Using Data Acquired by Mobile Device

    University essay from KTH/Geoinformatik

    Author : Kepan Gao; [2022]
    Keywords : U-Net; deep learning; tunnel monitoring; structural health monitoring; crack detection; mobile mapping system;

    Abstract : Infrastructures like bridges and tunnels are significant for the economy and growth of countries, however, the risk of failure increases as they getting aged. Therefore, a systematic monitoring scheme is necessary to check the integrity regularly. READ MORE

  6. 5. Development of a model-free damage detection algorithm using AR-models and its application to a riveted steel railway bridge

    University essay from KTH/Bro- och stålbyggnad
