A simplified calculation method for temperature evaluation of steel columns embedded in walls

Abstract: SUMMARYSteel elements behave differently in fire case when isolated or embedded in building walls. The walls on one hand have a favorable effect protecting the elements from the excessive heating resulting from the fire and on the other hand they have a detrimental effect due to the thermal gradients originated in the elements cross-section. The simplified calculation methods proposed in EN 1993-1-2 for fire design do not take into account the case of steel elements embedded in walls, stipulating only a formul… Show more

“…At time t = 2000 s, the PP coating is sliding rapidly down the face of the flange, demonstrating that the lower viscosity coating provides thermal protection for a shorter period. Embedding a structural steel element in a masonry wall changes its thermal response [11]. The thermal effect of a polyurea nanocomposite coating was studied for a steel beam embedded with the web perpendicular to the wall surface, as shown in Figure 15.…”

“…The numerical modeling is a widely used tool for solving structural engineering problems in fire situations. In turn, several previous studies demonstrate the efficacy of the software SuperTempcalc (Temperature Calculation and Design v.5) developed by FSD (Fire Safety Design, Sweden) when modeling heat transfer problems in structural engineering (Anderberg, 1991;Silva, 2005;Correia et al, 2011). This software belongs to the family of bidimensional modeling applications based on the finite element method.…”

“…Vale ressaltar que os métodos simplificados consideravam uma distribuição de temperatura uniforme na seção.Já emCorreia et al (2010b) são apresentados os resultados dos trabalhos anteriores e uma descrição dos efeitos do encurvamento térmico verificado neste estudo, além da comparação com resultados obtidos para pilares aquecidos uniformemente. Também é apresentado um modelo em elementos finitos desenvolvido utilizando o pacote computacional Abaqus considerando os ensaios com os elementos isolados e também com as paredes.…”
