“…In this regard, a time history of structural responses (i.e., displacement and velocity responses) and dynamic structural properties (stiffness and damping) are first estimated using the UKF and a measured acceleration input. Then, having estimated the desired states over time together with a proper definition of the failure criteria (from case studies, standards, or risk and safety analyses 44 ), we used the PDEM to estimate the time‐varying PDF of the structural response to be used for calculating the probability of crossing the limit state (i.e., structural failure probability). The joint PDF of the displacement ( X ), uncertainty vector ( θ ) of the physical parameters, and time ( t ) were estimated by solving the partial differential equation of PDEM (Equation ) 42 .…”
