Development of Short Span and Medium Span Footbridge Systems using UHPFRC in Czech Republic

---

Abstract

In the first part, this paper presents the experimental development of an innovative medium span footbridge system made of UHPFRC. The load bearing structure is designed as a U-shaped beam and consists of 2 main precast prestressed beams, which are connected with precast bridge deck segments. This system is different from the commonly used segmental footbridge structures because a longitudinal prefabrication is used. The development of this system was initiated for several reasons – no need to assemble a falsework and a formwork in situ, no need for heavy cranes, the main load-bearing structure does not contain transverse joints, a possibility to prestress the structure in advance in factory. In the other part, the article discusses another system of short-span footbridges made of UHPFRC designed and used in the Czech Republic. These footbridges are in the shape of a slab with ribs, and they are manufactured and placed on the substructure as a whole, so they represent an advantage especially in terms of construction speed and low maintenance requirements.
