Experimental tests and numerical modeling of cellular beams with sinusoidal openings

A Numerical Investigation into the Ultimate Strength of Steel Cellular Beams with Semi-Rigid Connections

“…Test setup and location of the measuring devices [15] For perforated beams, the outputs of the numerical simulations were validated using experimental measurements published by Warren [16] and Durif [17,18]. The test specimens denoted 1A, 2A, and 2B were part of eight cellular beams tested by Warren [16] at Natal University.…”

“…Example of test setup used by Warren [16] Three full scale cellular beams with six regular spaced sinusoidal web openings (Angelina beams), denoted ASO12, ASO16 and ASO18, were tested by Durif and Bouchair [16,17] at Blaise Pascal University. Beams ASO12 and ASO16 were made from a hot rolled IPE 450 in S460 and S235 steel grades respectively, while beam SO18 was made from an IPE 400 in S460 steel grade.…”

Validation of an analytical model for curved and tapered cellular beams at normal and fire conditions

“…4. [19] The internal forces N T,top , N T,bot and V Ed,T of the upper and lower members are calculated from the global bending moment (M Ed ) and shear force (V Ed ) at the mid-length of the opening considered using the Equations (1) and (2).…”

“…The shell element is particularly efficient to represent local instability with limited resources [25]. Existing studies on cellular beams showed that the shell elements represent well the behavior of cellular beams including the local instabilities as the webpost buckling for closely spaced circular openings [19,[26][27][28].…”

Estimation of Deflections in Cantilever and Fixed Castellated Beams with Hexagonal, Square and Circular Openings

“…Showkati et al [27] have tested simply supported CBs subjected to pure bending. Durif et al [28] investigated behaviour of CBs with sinusoidal openings and compared with circular openings. There are some other studies available in the literature on bending and buckling behaviour of castellated beams such as Abidin and Izzuddin [29], Yuan et al [30], Sonck et al [31], Sorkhabi et al [32], Wang et al [33,34], Ellobody and Young [35], Tsavdaridis et al [36], Sonck and Belis [37,38], Wang et al [39], Najafi and Wang [40], Grilo et al [41], Zaher et al [42] etc.…”
