Structural Modelling and Limit State Identification for Reliability Analysis of RC Containment Structures.

摘要

One of the most important ingredients in the safety analysis of any structures, and particularly nuclear structures, is the selection of an analytical model for the structure and identification of the limit states. An analytical model facilitates the evaluation of the significant structural response to postulated as well as actual loads, while a limit state represents a state of undesirable structural behavior which must be identified for the reliability analysis. Also, limit states must be specified in terms of response quantities obtainable from the analysis performed on the selected structural model. For the reliability analysis of a reinforced concrete containment structure, a SAP-V finite element representation (involving shell elements) is selected as the analytical model for the structures.
