Avaliação do método simplificado da ABNT NBR 14323:2013 no cálculo da elevação da temperatura em pilares de aço inseridos em parede

Abstract: Theoretical-Experimental Analysis of bending strength in Circular Hollow Sections Flanged Connections Resumo Devido às prescrições normativas não considerarem a flexão das ligações flangeadas para a determinação de sua capacidade resistente, se entende como necessário estudar esta influência teoricamente e experimentalmente. Neste trabalho, a flexão foi simulada considerando-se a excentricidade do carregamento axial de tração, variando-a de 0% até 24% do diâmetro externo do tubo. Com isso foi possível estudar … Show more

“…In the study of the temperature rise of the beams superimposed by slabs, the effects of the local radiation obstruction were considered, that is, the shading parameter of the profiles that are characteristic for acting in sections I and H determined jointly with the massivity factor from the geometric characteristics of the profile. Already for the columns, according to Neto [14], the correct behavior of these structural elements inserted in masonry stems from the action of the temperature gradient along its cross section, which is capable of leading to the appearance of bending moments and curvatures. In this way, because it was in favor of safety, it was admitted that the columns of the building of this study were completely surrounded by the flames of the fire.…”
