报告摘要:The structural reliability problem is time-variant when the characteristics of the structure or the applied loads vary in time. Structural characteristics may vary in time due to wear and tear, deterioration, or damage caused by applied loads. Applied loads on a structure are often stochastic in nature and produce stochastic dynamic response. Examples of such loads include excitations caused by earthquakes, and ocean waves. Since structural failures usually occur under extreme response thresholds, consideration of nonlinear response is essential for safety analysis.This talk will present a method for time-variant reliability analysis of structures using the First-Order Reliability Method (FORM). The Tail-Equivalent Linearization Method (TELM) will be presented as an alternative method of linearization to approximately determine the probability of failure of nonlinear systems. Comparisons will be made with the classical Equivalent Linearization Method (ELM).
