Abstract
Steel-reinforced concrete bridges with load-bearing tubular beams are effective for small and medium spans. The increased load-bearing capacity due to the elastoplastic operation of the tubular beam section reflects the relevance of their application in the bridge construction.
Purpose: The aim is to improve the section analysis using rational shape of the beam section and elastoplastic state.
Research findings: The improved section analysis of steel concrete tubular beams shows changes not only in bending, but also bending-torsional stiffness of sections in superstructures and identifies ways for their optimization.
