【 摘 要 】

The paper presents a summary of the development of bridge precast beams in EUROVIA CS company in the last years. Several types of beams are described. The first beam that has already been applied in real construction is an Omega beam which consists of shell outside envelope enabling construction of a bridge without intermediate supports in midspan. The second one is an inverted T beam for railway and road bridges. At present, the development of UHPC beams for footbridges is going on. The plan is to create a set of shapes and solutions usable for various configurations with spans up to 15 m, fully exploiting the UHPC advantages. Another element for bridge construction developed by Eurovia and its partners is the lost formwork panel used for bridge superstructures built from both concrete and steel beams.
