      Structural Health Monitoring (SHM) has become a powerful tool to help decision making for management of structures along their service life. Estimation of parameters from dynamic response is more appealing than doing it ...
    • Constrained observability techniques for structural system identification using modal analysis

      The characteristics of civil structures inevitably suffer a certain level of damage during its lifetime and cheap, non-destructive and reliable methods to assess their correct performance are of high importance. Structural ...
    • Dynamic observability method for durability assessment considering measurement noise 

      Peng, Tian; Casas Rius, Joan Ramon; Turmo Coderque, José (2020)
      Conference report
      Open Access
      Due to the inevitable degradation of material properties in structures in daily use, such as stiffness degradation due to cracking in concrete elements, their durability will definitely be influenced, and their serviceability ...
    • Planning low-error SHM strategy by constrained observability method 

      Peng, Tian; Nogal, María; Casas Rius, Joan Ramon; Turmo Coderque, José (2021-07)
      Article
      Open Access
      Structural identification using dynamical parameters (such as the natural vibration frequencies and mode shapes) is an important issue, especially in bridges or high-rise buildings. However, incorrect decisions could happen ...
    • Role of sensors in error propagation with the dynamic constrained observability method 

      Peng, Tian; Nogal Macho, María; Casas Rius, Joan Ramon; Turmo Coderque, José (Multidisciplinary Digital Publishing Institute (MDPI), 2021-05)
      Article
      Open Access
      The inverse problem of structural system identification is prone to ill-conditioning issues; thus, uniqueness and stability cannot be guaranteed. This issue tends to amplify the error propagation of both the epistemic and ...
    • Structural system identification by dynamic observability technique 

      Peng, Tian (Universitat Politècnica de Catalunya, 2021-05-21)
      Doctoral thesis
      Open Access
      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 ...
    • The dynamic assessment of structural condition by measurement error-minimizing observability method 

      Peng, Tian; Casas Rius, Joan Ramon; Turmo Coderque, José (CRC Press, 2020)
      Conference report
      Restricted access - publisher's policy
      The structural identification using dynamic parameters (such as the natural vibration frequencies and mode shapes of the structure) is an important issue especially in slender structures such as long-span bridges or high-rise ...
