Abstract
The use of high-performance concrete is leading to increasingly filigree structures, where their own weight relative to variable loads is becoming less and less. Material fatigue becomes relevant for such buildings. At the Institute for Building Materials Science at Leibniz Universität, Hannover, extensive fatigue tests has been carried out on normal-strength, high-strength and ultra-high-strength concretes [6]. This paper reports on experimental and theoretical tests on the fatigue behaviour of ultra-high-strength concrete. A fatigue model and a new design fatigue reference strength will also be presented. Both will be integrated into the design concept of Model Code. This enables the fatigue design of concretes with characteristic strengths up to fck = 200 N/mm2 under uniaxial pressure threshold loading for the first time. The developed fatigue model is based on extensive fatigue tests on ultra-high-strength concrete, and also caputures the fatigue behavior of lower strength concrete on the safe side.
