Verification of Existing Reinforced Concrete Structures Using a Semi-Probabilistic Method

Popis výsledku v původním jazyce

At present existing structures are mostly verified using simplified deterministic procedures accepted for design of new structures. This approach often yields conservative results and may lead to uneconomic upgrades. More realistic verification of actualperformance of existing structures can be achieved by a semi-probabilistic method in accordance with EN 1990 (2002) and ISO 2394 (1998) in which partial factors are derived from distributions of basic variables and given target reliability. This methodis easy to use and yet yields a well-balanced structural reliability. The present study intends to clarify applications of this method in verifications of existing reinforced concrete structures. A numerical example supplements general procedures and illustrates how the design values and partial factors can be derived for different target reliability levels and remaining working lives.
