【Abstract】 Discusses the problem of the structural reliability design for the intensity stress model. Gives the definition of equivalent exponential random variable.By using the concept, derives the explicit expression of the equivalent exponential dessign for the free distribution model and the exponential distribution normal distribution model, offers the formula of reliability coefficient. Compares the accurate reliability value with the designed value of the reliability of the exponential distribution normal distribution model and gives the relative error.更多还原
