    Structural system identification by dynamic observability technique 

    Peng, Tian (Date of defense: 2021-05-21)

    Structure system identification (SSI) can be classified as static and dynamic depending on the type of excitation. SSI by Observability Method (OM) using static tests was proposed and analyzed to address the observability ...

    Risk-based highway bridge inspection intervals 

    Anitori, Giorgio (Date of defense: 2021-04-23)

    Infrastructure maintenance programs establish schedules for routine inspections of highway bridges with little consideration of their current conditions. The time interval between two inspections is traditionally set based ...

    Seismic vulnerability assessment of traditional timber frame and masonry wall buildings : aplication to the historical centre of Valparaíso, Chile. 

    Jiménez Ramirez, Belén (Date of defense: 2021-01-13)

    The seismic vulnerability of urban assets exposed to earthquake hazard represents a growing concern in the engineering field due to the potential risk of collapse for the buildings, and the associated devastating consequences ...

    Integrated solutions for the energy and seismic retrofit of existing buildings 

    Lops, Camilla (Date of defense: 2020-12-15)

    European building stock is characterised by low energy efficiency and high structural vulnerability with respect to earthquakes, especially in seismic prone areas like Italy. In fact, the vast majority of buildings has ...
