“…However, the value of the interactive shear buckling is affected by global, local, and yield stress of the corrugated webs. Leblouba et al investigate the shear buckling and stress distribution in trapezoidal web corrugated steel beams. Results showed that the shear stress is at its maximum and uniformly distributed throughout the web until buckling, afterwards, it decreases and its distribution is uneven whereas the entire resistance is provided by the increased tensile stress.…”

Summary Studies on corrugated steel shear walls (CSSWs) generally indicate noticeable increase of energy absorption, as well as increasing shear buckling capacity of corrugated plates being more likely rather than the flat plates. In this paper, the effect of variation in the angle of trapezoidal plate on the behavior of CSSWs has extensively been investigated. Three specimens of CSSW with 1 story and single bay in half scale are tested under cyclic load. The observations of experiment do indicate that stress concentration has been increased in the corner of subpanels, by increasing of the corrugation angle. Development of the tensile field and wall yield and damage depends on the geometry of the plate. By increasing the corrugation angle, the stiffness and energy dissipation decrease; in addition, large loss of strength takes place. Comparing the numerical and experimental results indicates that for a closer look at behavior of trapezoidal CSSWs, fracture mechanics, fatigue, and damping of materials should be considered by numerical analysis.

“…That is why, based on the already existing practice of searching for methods to calculate beams with corrugated walls of different configuration [12][13][14][15][16][17]19], there was a need to address this task for the profiled plates, in particular, box cross section.…”

“…Comparison of analytical results with results of analysis of linear deformation by the method of finite elements demonstrated that the proposed modifications lead to an accurate prediction of flexural strength [16]. The existence of coefficients of local [12,18], general and combined [17] bending of a corrugated wall of the beam was experimentally proved. In addition, the authors noted the existence of residual strength that is roughly half of ultimate bearing capacity, regardless of the type of bending.…”

“…Results of nonlinear analysis of finite elements showed that stress tangents are distributed throughout the whole wall before outpressing, after which it decreases, and distribution becomes non-unified, while full resistance is provided by the increased stress. In [17], formulae for the estimation of shear strength were compared to current and existing experimental results. Comparison of existing analytical models for evaluation of shear strength in relation to the data of the test showed that [18] is accurate for economic modeling and general calculation.…”

“…Luo and Edlund [4] used numerical analysis of the finite element method to analyse the capacity of girders with corrugated steel webs and provided an equation for the ultimate capacity of the steel I-girder with corrugated web. Leblouba et al [5] pointed out that the post-buckling capacity of steel I-girders with corrugated webs is around 50 % of the ultimate load carrying capacity. Driver et al [6] presented experimental results on the shear strength of two large-scale steel I-girders with corrugated webs and verified the reduction effect of initial geometric imperfections on shear strength.…”

Scherverhalten von Balken mit Stegen aus Trapezblech – eine experimentelle Studie. In Forschungsarbeiten zum Scherverhalten von Balken mit Trapezblechstegen kommen gegenwärtig üblicherweise numerische Analysen mit der Finite‐Elemente‐Methode und kleinmaßstäbliche Versuche zur Anwendung. Allerdings können diese beiden Methoden kaum die Auswirkungen von Konstruktionsfehlern in realen Tragwerken berücksichtigen. Außerdem wurden in den meisten Studien an Balken mit Trapezblechstegen Doppel‐T‐Träger mit senkrechten Stegen und dünnen Flanschen als Forschungsobjekte verwendet, die ungeeignet sind, Balken mit geneigten Stegen oder Verbundgurten zu repräsentieren. Deshalb wurde ein Balken mit Trapezblechsteg und geneigten Flanschen im Originalmaßstab geprüft. Untersucht wurden der Versagensmodus und die Scherfestigkeit des Balkens. Die Ergebnisse zeigen, dass die Querkrafttragfähigkeit der Flansche nicht vernachlässigt werden darf. Die Out‐of‐Plane‐Verformung beginnt aufgrund anfänglicher geometrischer Unvollkommenheiten mit der Belastung des Stegs. Knickversagen tritt in denjenigen Bereichen auf, in denen die Out‐of‐Plane‐Verformung am schnellsten fortschreitet.
