STRUCTURAL SYSTEMS RELIABILITY UNDER STOCHASTIC LOADS

The present Paper deals with a formulation of structural system reliab ility for the situations when the applied loads must be modelled as no n-stationary processes. The structural systems considered herein may b e modelled as having the structural material either of the ideal rigid -plastic or of the linearly elastic type. In principle, the formulatio n can be extended to other material descriptions. The main advantage o f the presented formulation is that it allows the multi-dimensional in tegral required for outcrossing rate computation to be reduced to a on e-dimensional integral. The formulation is at the local member strengt h level and this also has advantages. An example application is presen ted and a comparison is given of the results for two kinds of structur al material assumption.
