A scientometric analysis on composite steel-concrete beam with openings: A review

This literature study investigates the mechanical performance of Steel-Concrete Composite Beams (SCCB) and load-carrying capability with web openings through detailed scientometric analysis. In general, structural engineers encounter a considerable challenge when limiting the height of their beam. The uneconomical floor-to-floor height is caused by the spaces used to transit pipes and ducts beneath the beams. Allowing pipes and ducts through web openings may reduce floor height. The initiative was thus to identify the load-carrying capacity of the steel-concrete beam with stiffeners placed next to openings. Therefore, the current research initiative focuses on the components of the SCCB, such as steel beam, concrete slab, deck sheet and shear connectors. The keyword and geospatial analysis were utilized for the four main research themes: SCCBs, shear connectors, deck sheets, and web openings. The investigation found the correlation between each parameter and summarized the studies, such as numerical, analytical, and experimental, on designing a steel-concrete composite beam with web openings. More peculiarly, the finite element analysis using software like ABAQUS and ANSYS was utilized for the analytical studies. The deck sheet provided in the beam reduces the self-weight and increases the load-bearing capacity of the SCCB. The complication in providing web opening is that the load-bearing capacity of the SCCB will be reduced, which can be compensated by providing additional stiffeners. From this study, the circular web opening with stiffeners has fewer stress concentrations, lesser load deformations, high stiffness and load-bearing capacity compared to other web openings.
