FIELD: bridge building.
SUBSTANCE: invention relates to the field of bridge building. The truss consists of a pipe. The ends of the pipe are closed with upper and lower plugs, forming a closed space, which is filled with tension concrete or fiber-reinforced concrete to form a concrete core of the truss. The concrete core is connected to the truss tube by means of radially welded reinforcing bars.
EFFECT: increasing the reliability, durability and load capacity of the truss and reinforced concrete support, reinforced concrete crossbar in the installation area of the truss.
