![]() ![]() Based on these test results, new Woehler curves and a new approach to the fatigue design of normal-strength, high-strength and ultra-high-strength concrete under uniaxial compressive fatigue loading was developed in, and subsequently developed further. Keywords: fatigue, design model, high-performance concrete, Model Code 2010 1 Introduction purpose of comparison. This new design model is included in the new fib Model Code 2010. A comparison between the new design model and the current standard ones reveals that the new design model ensures safe and economical design of normal-strength, high-strength and ultra-high-strength concrete. A new design model for compressive fatigue loading and its derivation is presented in this article. Considering comprehensive knowledge now available concerning the fatigue behaviour of normal-strength and high-strength concretes, the amount of this reduction can no longer be justified. In addition, the design rules include a strength-dependent reduction in the fatigue reference strength, which leads to uneconomical design of high-strength concrete.
