Abstract

This article focuses on bridges with beams of combined cross section made of glued wood and reinforced concrete. The main purpose of the study is to compare the key characteristics of reinforced concrete, glued wood, and combined bridges. The comparison is based on three main parameters: cost, operational lifespan, and load capacity. The innovation of the use of glued wood in the construction of bridges lies in a combination of the strength and elasticity of wood with the strength and durability of reinforced concrete, which allows you to create more stable and economical structures that can withstand heavy loads. An analysis of the main characteristics of these such bridges allows us to conclude that the advantages of such a combination of materials over other types of bridges. The data obtained can be useful for designers and builders when choosing optimal material for the construction of a bridge structure.
