A Novel Rectangular-Section Combined Beam of Welded Thin-Walled H-Shape Steel/Camphor Pine Wood: The Bending Performance Study

At present, the development of green building materials is imminent. Traditional wood structures show low strength and are easy to crack. Steel also prone instability. A novel rectangular-section composite beam from welded thin-walled H-shape steel/camphor pine was proposed in this work. The force deformation, section strain distribution law, damage mechanism combined were studied optimize design, clarify stress characteristics, present a more reasonable efficient cross-section promote environmental protection techniques. Furthermore, effect different factors such as steel yield strength, H-type web thickness, height, flange upper covered-board width investigated. ABAQUS simulation with finite element software performed verified through empirical experiments. According results: (1) process divided into three steps, namely elastic stage, elastic–plastic step, destruction cross-middle met flat assumption; (2) additionally, bond connection reliable, two deformations consistent, combination significant. study main showed that an increase H-beam caused significant enhancement bending bearing capacity. led high stiffness, capacity, good ductility under bending.
