Abstract. The problem of calculating pedestrian railing made of polymer composite materials on bridge structures is analyzed. It is noted that, although methods for calculating various products and structures made of polymer composite materials have been sufficiently developed, however, methods for calculating pedestrian railing are still just beginning to be developed. Normative methods for calculating pedestrian railing are very primitive and do not take into account all the features of their work.

The article discusses the application of the finite element method to the calculation of pedestrian railing, and in addition to standard loads, the effect of the wind load and the joint work of the pedestrian railing with the span are taken into account. It is shown that the joint work of the pedestrian railing with the span, even under static loading, has a significant effect on its stress-strain state, increasing it, which in certain cases, in the presence of installation defects, leads to the destruction of the pedestrian railing from polymer composite materials.

Key words: pedestrian railings; bridge construction; polymer composite materials; pedestrian railings modeling; pedestrian railings defects; pedestrian railing stress state
