Bridge Applications

Design and Production of a Segmental Prestressed UHPFRC Bridge in Pribor

---

Abstract

This paper deals with the design, production and assembly of a segmental prestressed footbridge made of UHPC (Ultra High Performance Concrete) which is sometimes referred to also as UHPFRC (Ultra High Performance Fibre Reinforced Concrete)and installed in the Town of Příbor. The UHPFRC or UHPC material gradually finds its way to interesting and unique structural applications in conditions of the Czech Republic. The paper presents the design, production and assembly of a segmental footbridge, the first of its kind in the territory of the Czech Republic, designed as a simple beam with a span of 35 m and a total length of 36 m, which is formed of the bracing of 5 two-chamber segments with a width of 2.5 m and a height of approx. 0.8m. The structural material selected was UHPFRC of the C110/130 class with dispersed steel reinforcement which was developed in the Klokner Institute (KI) and optimised and operationally tested atKŠ PREFA s.r.o., according to the design drawn up by architects and the Novák & Partner company in cooperation with the KI staff.
