“…It should also be noted that the yield lines do not propagate to the top flanges of the plate girder. This behavior is different from what can be observed in conventional solutions with a flat web [11], where yield lines appear near the applied load, immediately next to the interface of the flange with the web.…”

“…During the numerical investigations, it was also observed that the shear stress distribution at the corrugated web was the same in all analyzed beams (Figure 14). Shear stresses were distributed evenly onto the corrugated web before buckling, and they reached the highest level just after the appearance of buckling [11]. The post-buckling stress distribution itself varies depending on the location of the cross section on the corrugation.…”

“…The stiffness of the web can also be increased by using profiled corrugated plates, which provide better local stability than girders made of rolled sections and conventional plate girders with a flat web [4][5][6][7][8]. Corrugated plates may have various shapes, e.g., trapezoidal, triangular, channel, cellular, or sinusoidal [9][10][11].…”

This paper presents the results of numerical investigations into the behavior of a sinusoidal web loaded in shear due to buckling in the period from the onset of buckling until failure, as well as the impact of a reinforced concrete slab on the stability of the web. The analysis concerned steel girders and composite girders with the top flange bonded to a reinforced concrete slab. Nonlinear analyses were performed using the finite element method. The results of the investigations support the conclusion that the appearance and propagation of shear stresses in the sinusoidal web of the composite steel–concrete beam are the same as those in an identical non-composite steel beam, but the bracing of the top flanges improves the shear strength and, at the same time, affects the location of initial stresses. In addition, it was found that, despite the three types of buckling, the predominant failure of the sinusoidal webs, regardless of the presence of the concrete slab, is global buckling. It occurs diagonally through several folds at the same time, including deformation of the web over its entire height.

“…Moon et al [15] proposed a global shear buckling coefficient, Pasternak and Kubieniec [16] discussed EN rules for designing corrugated web Ibeams and He et al [17] studied numerically partially encased I-girders with different material and geometric parameters. In following years numerical analyses concentrated on shear were carried out by Hassanein and Kharoob [18], Hassein et al [19], Leblouba et al [20] and Riahi et al [21], where girders with flat web and the corrugated web were investigated in a parametric study with 10 main parameters. Shear strength was also studied numerically for tapered bridge girders by Zevallos et al [22], who observed a reduction of strength together with an increase of tapering angle.…”

The main aim of this work is a computational nonlinear analysis of a high strength steel corrugated-web plate girder with a very detailed and realistic mesh including vertical ribs, all the fillet welds and supporting areas. The analysis is carried out to verify mechanical structural response under transient fire temperature conditions accounting for an efficiency and accuracy of three various transient coupled thermo-elastic models. All the resulting stress distributions, deformation modes and their time variations, critical loads and eigenfrequencies as well as failure times are compared in all these models. Nonlinearities include material, geometrical and contact phenomena up to the temperature fluctuations together with temperature-dependent constitutive relations for high strength steel. They result partially from steady state and transient experimental tests or from the additional designing rules included in Eurocodes. A fire scenario includes an application of the normative fire gas temperature curve on the bottom flange of the entire girder for a period of 180 minutes. It is computed using sequentially coupled thermo-elastic Finite Element Method analyses. These account for heat conductivity, radiation and convection. The FEM model consists of a combination of 3D hexahedral and tetrahedral solid finite elements and uses temperature-dependent material and physical parameters, whose values are taken after the experiments presented in Eurocodes. Numerical results presented here demonstrate a fundamental role of the lower flange in carrying fire loads according to this scenario and show a contribution of the ribs and of the welds to the strength of the entire structure.

“…As far as the shear strength is concerned, studies carried out so far [ 19 , 20 , 21 , 22 , 23 , 24 , 25 ] have shown that it is provided only by the web. Consequently, the interaction between the bending moment and the shear force can be omitted when determining the shear resistance [ 26 , 27 , 28 ].…”

This paper presents the results of experimental investigations performed on beams with corrugated webs. The aim of the research was to determine the effect of the geometric parameters of the sinusoidal web on the behavior of I-beams subjected to four-point bending. Special attention was paid to the effects of web thickness and wave geometry on the deflection of beams. The obtained failure modes of particular test samples are presented. Reference has also been made to the determined standard load capacities based on Annex D of the EC3 standard. In order to compare the performance of beams with corrugated webs, the results for beams with flat webs of the same thickness of web sheets are also presented.
