AI Technical Summary
Existing technologies struggle to accurately assess the reliability of structures under dynamic loads, especially when structures such as bridge main beams face wind loads and vehicle dynamic loads. Existing non-probabilistic reliability models cannot effectively capture and evaluate time-varying reliability.
A time-varying ellipsoidal model is adopted. Response samples are obtained through dynamic simulation or sensors, discretized into sub-intervals, and sample points are generated. The time-varying ellipsoidal model is established to determine the failure area and calculate the instantaneous span rate to evaluate the structural reliability.
It can accurately assess the structural reliability under dynamic load conditions without requiring a large number of probability distribution samples, improving the accuracy and engineering applicability of the assessment results and breaking through the limitations of traditional models.
