[CS3-17] Development of non-metallic precast bridge railing
Keywords:Ultra high durable bridge railing, Precast, High strength fiber reinforced concrete, Glass FRP rods, Collision test
Bridge railings of expressways is required to be highly durable because it is exposed to the environment.
This paper discusses the development of a non-metallic precast bridge railing with the goal of developing a highly durable bridge that does not use any steel members such as reinforcing bars.
To make the parapet non-metallic, based on the generally used highway bridge railing forms, we developed a precast bridge railing using GFRP rods instead of rebars. During the development, a collision test was conducted using a specimen with an approximate load capacity of 70 kN.
The test confirmed a safety level equivalent to or higher than that of a typical reinforced concrete bridge railing.
