Temperature analysis of steel structures protected by intumescent paint with steel claddings in fire
Popis výsledku v původním jazyce
It is of great interest to understand the stabilization effect of steel structures by steel claddings in fire. Structural fire analysis using finite element method including temperature analysis and structural analysis is important to investigate the stabilization effect. However, temperaturedependent thermal material data for insulation layer of sandwich panels and the intumescent paint for fire protection of steel sections are still scarce. In this paper, the available thermal properties of these materials from literature are summarized, and 2D and 3D temperature analyses are carried out for steel sections with steel claddings such as sandwich panels with mineral wool and PIR cores and trapezoidal sheeting with mineral wool insulation. The analysis results are compared with the fire tests conducted in RFCS STABFI project. The study shows reasonable accuracy of modeling using existing thermal material data for temperature-dependent insulation properties and thermal data for intumescent paint. Gaps for further research are identified. Study also shows the heat sink effect of steel section by sandwich panels with mineral wool core. Therefore, it is recommended that the sandwich panels should be included in the thermal analysis model for steel sections with sandwich claddings.
