Calculation of the flying structure of peshekhodny bridge from polymeric composite materials
One of the solutions to the problem of pedestrian safety in the streets of modern cities is the construction of pedestrian crossings. The process of their construction, often accompanied by the need for overlapping roads. This leads to disruption of traffic, the appearance of traffic jams. The period of installation of the span structure directly depends on its weight. To reduce the value of the latter by a factor of several by completing the construction of a span structure from modern polymer composite materials (PCM). A study was made of a pedestrian span standing in the form of a truss made of fiberglass pipes, the experimental design of which was taken from existing metal trusses. This article presents the procedure for conducting research work: selection of dimensions, basic calculations and results for each of them. At the end, the total weight of the calculated fiberglass truss is compared with its analog of steel profiles.
