Abstract

The use of steel-concrete composite beams with web openings becomes an advantageous tool used to reduce the height of the floor, as the web openings allow the integration of hydraulic and electrical services. This study aims to investigate the web-post buckling resistance of steel-concrete composite beams with elliptically-based web openings. A finite element model is developed to predict the behavior of steel-concrete composite beams with elliptical-base openings, considering experimental analyses. The numerical simulations are processed in two steps: buckling and post-buckling analyses. A parametric study is performed based on the geometric parameters of the openings, as well as the spacing between them. Increasing the slenderness of the web tends to change the failure mode, changing from web local buckling to web-post buckling, where the presence of the concrete slab and the ellipticaly-based openings contribute to the resistant capacity of the composite cellular beams.
