Abstract

What means „Design Service Life“ in the durability concept of car parks?. For years national and international research works on performance-based durability design concepts have been performed to improve economy and durability of concrete structures with a differentiated estimation of member resistance (solidity and cover of concrete) under different environmental conditions. First concepts already have been tested on specific projects. The present state of science – partly state of the art – and the chances and risks by using performance-based durability design concepts are presented in this article. As an example the descriptive requirements according to the present German standards and the performance based design of the resistance against chloride induced corrosion (XD-exposition) are compared and explained in detail. Furthermore the present knowledge of the corrosion intensity of reinforcing steel in cracks is summarised, in which chlorides were penetrated during one winter saison. This question is essential for reinforced concrete structures in car parks with and without surface protection systems. This is also a topic in the DBV-Guide-to-Good-Practice „Multi-storey and Underground Car Parks“.
