“…Thereby, by applying initial geometrical imperfections, it must be turned into a problem with continuous response rather than bifurcation. Usually, the probable constructional distortion of steel plates is considered as a multiple of the first mode shape of buckling obtained by an elastic buckling analysis (Broujerdian et al, 2015, 2016; Graciano et al, 2011; Reis et al, 2016b). In this article, applying shear load on two sides of the middle stiffeners using ABAQUS shell edge load command, first eigenmode of each girder is obtained by linear buckling analysis.…”

“…Initial imperfection with a shape compatible with the first buckling mode decreases the strength more than other shapes. On the other hand, increasing the imperfection amplitude causes reduction in the ultimate strength (Broujerdian et al, 2016; Chacón et al, 2010a; Garlock and Glassman, 2014; Graciano et al, 2011; Reis et al, 2016a, 2016b) For structural plate elements, in the absence of a high-precision analysis of the geometric imperfection, 80% of the essential manufacturing tolerance for welded profiles (0.8D/100) may be used as the equivalent geometric imperfection at both ambient and elevated temperatures (Chacón et al, 2010a; EN 1993-1-5, 2006; Graciano et al, 2011; Reis et al, 2016a, 2016b), where “D” denotes the web depth of the plate girder. Thereafter, the initial shape of girder in nonlinear static analysis is assumed to be compatible with the first buckling mode of the girder with the amplitude of 0.8D/100.…”

In literature, there is no theoretical research focusing on moment–shear interaction behavior of the hybrid girders. This article investigates the moment–shear interaction behavior of non-composite hybrid steel plate I-girders at ambient and elevated temperatures. In this regard, based on a more realistic distribution of bending and shear stresses, theoretical equations have been proposed to achieve the moment–shear interaction curve without considering shear buckling. The results obtained from the proposed equations were compared with the results of the existing experimental data and those of the finite element analysis. According to the results, there is good agreement between them.

The girders or parts of the girders are not ideally flat in terms of their geometry. The deviations that occur are defined as geometric imperfections. Also, in the material from which the girder is made, a certain deviation may occur during factory production or for some other reason, which is known as structural imperfection. This paper presents the analysis of the behavior of plate girders (welded steel I girders), with and without material stiffening and loaded with patch loading. The results were obtained by numerical simulation in the ANSYS for models with included geometric imperfections. The model was performed in accordance with the recommendations for different behavior curves of materials from Eurocode 3. The limit load obtained by numerical simulation corresponded to the experimental results from the literature. Stress values for girders with and without geometric imperfections for the same load value were compared.

“…Thickness of the web, distance between transversal stiffeners, yield stresses of the web, distribution lenght of the load, the existence of longitudinal stiffeners, ets. In particular, the imperfections of the girder both geometrical and material are significant and have been the subject of research during past decade [5].…”

Starting from the differential equations of elastic surface it is determined the critical buckling load of the rectangular plate. Especially, we consider the case of the local buckling of web due to the load that acts on the plane of the web. The concept of two basic methods is presented: the method of effective width and reduced stress method. These methods are recommended by European standards. An example of the buckling of welded plate girder subjected to partially distributed load with the increase of force until the ultimate load by numerical simulation is done.
