Local buckling of cold-formed elements used in arched building with geometrical imperfections

The Preliminary Uniaxial Compression Behavior of Corrugated Cold Formed Steel Members

“…In 2014, Cybulski et al carried out some experiments on MIC120 models and the experimental results of this work are compared with the experimental results of Cybulski et al research in Table 3 [5]. It should be noted that, the model thickness of the mentioned research was 1 mm and length of model was 600 mm, while the model thickness of this work is 0.6 mm and length of model is 1200 mm.…”

“…Thus, the use of Eurocode 3 Part 1-3 [10] for coldformed elements is omitted and only cross sections of effective widths are used to make the necessary allowances for reductions in resistance due to the effects of local buckling. The post-critical load carrying capacity for cold-formed element is described in the Cybulski et al [5]. They used the Eurocode 3 to calculate the post-critical load carrying capacity [10,29].…”

“…They used the Eurocode 3 to calculate the post-critical load carrying capacity [10,29]. In this research, the post-critical load carrying capacity was calculated same as Cybulski's et al [5]. So, the post-critical load carrying capacities are equal to 57.96 kN and 79.38 kN for with and without corrugated models, respectively.…”

Plieninių Šaltai Lankstytų Elementų Varžtinių Mazgų Tyrimai

“…Pagrindinės klupties rūšys (1.3 pav. ), labai pavojingos šiems elementams, yra tokios: vietinė kluptis (Cybulski et al 2014), iškreipiamoji kluptis (Maduliat et al 2015), bendroji kluptis, šoninė sukamoji kluptis kolonoms ir šoninė kluptis sijoms (Hancock 2003). Išlankstyto elemento mechaninės savybės nedaug skiriasi nuo lakšto, kuris buvo naudotas elementui išlankstyti.…”

Application of 3D digital image correlation for development and validation of FEM model of self-supporting metal plates structures

“…Such structures were initially built as temporary buildings used for military purposes. Direct adaptation of this technology for civil purposes, combined with extending the lifetime and changing of environmental conditions, have caused design problems, especially in terms of stability and load transfers [1][2][3]. In order to ensure safety and proper operational parameters during lifetime, hybrid experimental-numerical methods are being used in design and exploitation stages [4].…”
