Research output: Contribution to journalArticleScientificpeer-review


The idea of the durability design of concrete structures is developed as statistical theory which is based on the probability of failure taking into account the time as a parameter of the performance function and of the loading function. The generalised loading includen environmental effects into the structure like mechanic loading and weathering (sun, temperature changes, frost, moisture, pollutants, oxygen etc.). As generalised capacities like loading capacity, tightness, deflections, cracking, smoothness of the surface and visual fitness are treated. The statistical theory is transformed into practical deterministic durability design applying partial safety factor method. Important addition into the ordinary partial safety factors is the lifetime safety factor which is introduced into a design for first time here. The static and dynamic performance parameters and the durability performance parameters are combined together in the final phase of design. Performance and service life calculation models is introduced into design method, and presented for six decradation processes. The article is based on the report of RILEM TC 130—CSL [31], where the author was serving as chairman.
