Reliability Assessment of Extraordinary Structures

Since there is insufficient experience in the evaluation of reliability of exceptional structures and relevant standards do not apply, some categories of such structures are detailed here. Based on a distinction of reliability between ordinary and exceptional structures an analysis of these two classes of structures has been made at the level of partial factors. The partial factors values have been analysed for the Reliability Class RC2 according to EN 1990 whose numerical values are contained in the stated standard so that the Reliability Class RC2 can be listed among ordinary structures. On the other hand, standardized partial factors for RC2 are compared with the computed partial factors in this paper for RC3 and which are not contained in standard EN 1990 so that this class of structures can be classified among exceptional ones.
