Structural Dynamic Reliability under Fuzzy Loads with Some Times and Fuzzy Strength

Abstract

Abstract: For the some times fuzzy loads and fuzzy structural strength in the practice engineer, the fuzzy several times dynamic loads and the structural fuzzy strength are analyzed. The prediction models of the structural dynamic fuzzy reliability are established by using the stress-strength interference theory when the several times fuzzy loads changes over time and the structural strength changes without degeneration and with degeneration. The fuzzy reliability is converted to the probability reliability by using the level-cut method to solve. It is shown that the models are feasible and reasonable by an example.
