Abstract
An extensive test programme on Ultra High Performance Concrete (UHPC) has been started at the Chair of Structural Concrete of Kassel University in summer 2004. The purpose of these investigations is to analyse the interaction of steel fibres and conventional bar reinforcement under tensile stress as well as the influence of cracking on the compressive strength of UHPC. The tests are conducted on panel-shaped structural members and on tensile members with different cross-sections. The objective of these tests is to develop constitutive models for cracked UHPC under tension and under compression. Based on this, calculation methods for ultimate limit state (ULS) as well as for serviceability limit state (SLS) shall be derived (calculation of crack width and deflections, ultimate limit state design).
