Features of the design of bridge structures made of composite materials
Incoming article date: 11.04.2019The article discusses the use of reinforced polymer fibers in architectural and structural design of bridges on the example of structures in the Netherlands. The chemical structure of this material is presented - a polymer matrix reinforced with natural or artificial fibers. A brief historical background of the use of composite materials is given, a comparative analysis of structures made of new construction material and the traditional one is carried out. The problems and possibilities of this relatively new material are discussed. The variants of constructive solutions for the bridge construction of a new generation are proposed. The basic methods for the production of bridge components that meet aesthetic and economic requirements are described: the use of modular elements of the edges of the flooring, the construction of smart formwork and monocoque structures. The physicochemical properties of polymeric materials have been studied in detail, of which it is currently possible to manufacture reinforcement for bridges. In conclusion, the analysis of the effectiveness of the use of this material in architecture and construction over the past decades has been carried out and suggestions have been made about the future vector of the study and application of polymers.
