【 摘 要 】

UHPC has a number of unique properties, which stands over conventional concrete. The demand for these high performance properties predetermines some elements as typical representatives for the use of UHPC. For this reason, the range of use of UHPC elements is very wide. This article deals with the numerical design and assessment of the three variants of UHPC slabs forming permanent formwork of reinforced concrete bridge deck of the footbridge. Utilisation of outstanding properties of UHPC in this special case would enables unique and easier way of construction of this bridge.
