Análise térmica bidimensional de perfil de aço sujeita a elevadas temperaturas

Artigo completo:

The present article aims to study the thermal behavior in a H profile of steel with and without boundary thermal protection of uniform thickness by finite element method. In this way, the procedures based on the Galerkin weighted residue method are applied. Numerical experimentation is conducted by the behavior of the temperature in the center of the web for different levels of time of exposure to fire and by parametric analysis of the thickness of the protective material. In summary, the program developed for solution presented a good adjustment in relation to the numerical answers obtained in the literature.
