Abstract
The deformations during the service life of concrete structures are predicted using creep models, assuming a constant loading. However, many structures are not only subject to static creep loads but to cyclic loads as well. The supeiposition of both load types can lead to significantly increased concrete deformations compared to deformations predicted by existing creep models. This might result in serious damage and safety risks. Hereinafter, the viscous strain development of a nomial-strength concrete due to static creep and cyclic loading under corresponding stress levels are presented. The results show that even for low stress levels of Smax ≤ 0.45, there are differences in the cyclic and creep strain curves. For higher stress levels, the influence is expected to be even more significant. Therefore, an adjustment of current dimensioning models is necessary.
