Abstract
The compressive strength of ultra-high performance concrete (UHPC) which is comparable to structural steel and can be advantageously used in thin construction elements. Because of its extreme brittle fracture behaviour innovative concepts for design and casting procedure are necessary different from traditional concrete engineering. Slight UHPC-tubes which are covered by thin-walled steel tubes should be designed as compressive struts for large scale frameworks. Experiments with tubular columns (hollow profiles) demonstrate the ductility-increasing effect of these steel covered plain UHPC-tubes. In opposite to the composite or sandwich engineering the axial load bearing capacity should be generated prior by the pure concrete cross section. The steel cover is designed in order to serve as minimum reinforcement, therefore its thickness is to be minimized to achieve an economic optimum but still ensure ductile fracture behaviour.
