Global factors for reliability verification of reinforced concrete structures

Abstract eng:
The concept of global resistance and load factors provides a rational approach to reliability verification of reinforced concrete structures that require non-linear or dynamic analysis. In such cases the mean values of basic variables need to be used in the analysis to determine adequate structural response. Reliability of these structures can be then conveniently verified using results of the analysis and the global resistance and load factors. The submitted proposal for the specification of global factors is based on probabilistic analyses of selected structural members (slab, beam and column). It appears that the global resistance factors are dependent on the type of structural members and on reinforcement ratio. The global load factors are strongly dependent on load ratio of variable and total actions and type of action. The total reliability factors can be further defined as products of the global resistance and load factors.
