【 摘 要 】

Reinforced concrete superstructure type »filler beam» would be appropriate in future reconstruction of such structures with span length of 5 - 30m. They can be applied in road and railway bridges as their advantages are significant. They have a small construction height, simplified installation, steel elements are simplified and produced in factory conditions, less formwork, as well as easy maintenance in operation. This type of structure would be appropriate in urban environment as besides the above - mentioned advantages, it also has low noise emission during the passage of vehicles.
