Since the 1990s, road rail has once again become a key element of public transport
in liveable modern cities. The design of these structures is greatly complicated by
their complexity and the limited availability of data on the pouring material. While
the railway designer typically deals only with the rails and the pouring material,
the structural engineer, ignoring these elements, often considers only the supporting
beam as a single structural element. Breaking with this approach, a method is presented
that, when implemented in an MS Excel environment, can be used to create an efficient
tool for the joint analysis of the embedded rail structure and its supporting beam.
The internal forces in the beam obtained by this method are more favourable than those
calculated by the conventional method and thus provide the opportunity to optimise
(minimise) the amount of material used. In this article, we present the potential
applications of the complex model and, based on the calculations performed, highlight
the material savings that can be achieved in the design of the supporting beam, which
also proportionally reduces the costs, which are limited in the changing economic
environment.
