Simulação numérica do comportamento estrutural de vigas casteladas de aço com ênfase na flambagem do montante de alma

Abstract: RESUMOEste trabalho apresenta um estudo numérico sobre o comportamento de vigas casteladas fabricadas a partir de perfis laminados, com ênfase na instabilidade do montante de alma. As análises foram realizadas utilizando um modelo de elementos finitos, desenvolvido com o software ABAQUS, validado com resultados de quatro programas experimentais. O modelo considera a influência de tensões residuais e imperfeições iniciais e inclui análise de instabilidade e análise não linear material e geométrica, simulando o … Show more

“…8 illustrates their parameters) with an expansion ratio equal to 1.5. This value is usual for the alveolar profile, used by several authors in their experimental and numerical works (Zaarour and Redwood [30]; Bezerra [31]; Vieira [32]). The parametric study was performed considering four heights, d g , 300, 600, 900 and 1200 mm, covering large and small heights.…”

“…Variations in the cut pattern allow for a wide variety of geometries. According to Vieira et al [2] the Anglo-Saxon (Figure 1a), Peiner (Figure 1b) and Litzka (Figure 1c) types are the most used. The main advantage of castellated elements is the increase in flexural stiffness with a lightweight structure.…”

“…O estudo de modelos do montante de alma isolado em vigas alveolares já foi realizado por diversos autores (PANEDPOJAMAN et al, 2014;VIEIRA, 2015;GRILO et al, 2018b;JUSTINO, 2018). No entanto, não há consenso sobre as condições de contorno ideais a serem adotadas para o montante.…”
