“…On the other hand, considering composite cellular beams, the studies dated back to the early 2000s. In the literature there are studies considering composite beams with only a rectangular web opening with solid [32][33][34][35][36][37][38][39] or composite slabs [13,[37][38][39][40][41][42][43][44][45][46][47][48], and composite plug systems with perforated beams [52][53][54][55][56]. In the latter case, one of the benefits is that WPB and VM cannot be achieved as the thin-walled perforated section with large closely spaced web opening is partially encased by concrete (one opening every other metal deck rib) which also acts as a shear connector with the concrete passing through.…”

“…Despite this, unabated demand for wider implementation of these structural elements has been witnessed and has yielded an estimable number of studies covering a large domain of related structural issues. In relation to the scope of this research, a quite extensive assemblage of research works published by Granade [3], Todd and Cooper [4], Clawson and Darwin [5], and Redwood [6] has set the cornerstone for the current state of resistance calculation. In fact, the latest unified design approach can be found in the work of Lawson [7].…”

As far as research into the field of composite steel and concrete beams with web openings has shown, the initiation of a complex stress state due to the introduction of web openings is, unfortunately, inevitable. As a logical consequence, estimation of the resistance becomes complex as well. Aiming to provide a more convenient approach, especially for evaluation of the bending resistance to the Vierendeel effect with the presence of high shear forces, a marked simplification with respect to quantification of the shear force redistribution between T-sections is presented. This novel approach stands on strong fundamentals of experimental evidence and parametric finite element (FE) investigation. Concretely, within the experimental part of this investigation, the load response of four composite beam samples was recorded and profoundly analyzed. Subsequently, a detailed FE analysis in the software ANSYS 2024 R1 (ANSYS Inc., Canonsburg, PA, USA), exploiting its parametric design language (APDL), was conducted. Finally, concise data compilation and their comprehensible interpretation were enabled by employing the software MATLAB 2024a (The MathWorks, Inc., Natick, MA, USA). In view of this treatment, a cornerstone for successive assessment of the obtained data was laid. Attempting to identify the key factors influencing the shear force proportion between the tees, integration of the shear stresses along the vertical sections with regular spacing along the FE beam models was conducted. By virtue of this concept, not only the magnitudes of the shear forces for the tees were obtained but also the leading importance of the opening depth was demonstrated. Furthermore, a complete picture of the shear force behavior along the composite perforated beams was derived. On this basis, a novel method representing a simpler and more accurate form of estimation of the shear force proportion for T-sections was proposed.

“…There are studies on composite beams with only a rectangular web opening, considering solid [19][20][21][22][23][24][25][26] or composite slabs [4,5,[32][33][34]6,7,11,[27][28][29][30][31]. The present paper focuses on studies of composite cellular beams, which are recent; mainly those initiated in the 2000s.…”
