This research addresses a critical issue in composite sections—insufficient concrete flow on both sides of the steel beam web, leading to discontinuity in the filler material. The study focuses on double honeycomb beams in concrete-enclosed steel structures, categorizing them as pure and enclosed steel. A two-phase approach, comprising experimental and numerical analyses, was employed. Fabrication of specimens representing both beam types was followed by bending tests using the STD600 apparatus. The primary specimen showcased the significant advantages of composite beams over conventional steel in bending scenarios. In the experimental phase, two practical solutions were introduced—transforming beam profiles into honeycomb configurations and optimizing spatial constraints around the central linear variable differential transformer (LVDT). Finite element models, validated against test results, demonstrated the practicality and accuracy of Abaqus software. The findings highlight superior flexural behavior in composite beams, presenting promising implications for the construction industry. |
