| Abstract: | Based on discussion of the characteristics of JC method, a method called dynamic coordinate transformation method is brought forward; this method can solve the problem of how to determine the structural design-parameters under required reliability. Also the keypoints about how to use this method with common function and normal variables that are mutually independent and accord with normal distribution are proposed. Further more, the problem of how to solve the structural design-parameters under required reliability while the problem are about multi-function are solved. |
