Research of Efficiency of Using Carbon Fiber in Arnored Concrete Spans of Railway Bridges

Abstract

Purpose. This work presents using carbon fiber as composite rebar by way of rods of fittings for reinforcement armored concrete span 13,5 meter length compared to same-length span with usual fixture. Methodology. The calculation is carried out as described in the methodological guidelines for the design and calculation of concrete span with frame-welded fittings. Findings. On the basis of the above study was to determine how the use of composite reinforcement as working for the reinforcement of its span. Originality. The possibility of using composite rebar as an element that works in tension in the span was proved. Practical value. Install valves of this type will reduce the cost of the span and increase its operating period.
