【Abstract】 The method for evaluating checking point in the four-moment structural reliability ana- lysis it presented,the formulas for calculating four-moment of safety margin function respresented approximately by Taylor Series expansion about checking point is established.The method can be used not only for prediction of structural reliability,but also probabilistic-based design,thus,forms the base to establish design formula for practical purpose using four-moment reliability theory.更多还原
