摘要

In this article research on the fatigue behaviour of Ultra High Performance Concrete (UHPC) under cyclic loading at TU Miinchen is shown. Due to the slenderness of UHPC-structures the fatigue performance gains outstanding importance. High compressive strength in comparison to small tensile strength of UHPC requires prestressing. In service cyclic loading in compressive-tensile stress range can occur. In classical S-N-curves the effects of relevant parameters on the fatigue behaviour of UHPC are shown, e.g. stress variation and mean stress, fibre ratio, fibre orientation and heat treatment.
