Comparative analysis reveals cost differences in steel, steel-concrete, and steel-timber beams, highlighting material efficiency.
<ns3:p>In this paper the material costs of beams made of different materials were compared. Steel and steel-concrete composite beams were compared with a steel-timber composite beam. In the case of a ceiling composed of beams and slabs, steel-timber composite beam had the most favourable bending resistance to mass ratio.</ns3:p>
