The fire tests were carried out according to the standard temperature\/time curve (STC) on HEB 320 steel profiles, each with and without previous sooting. The results show that sooting leads to significantly higher emissivity. The publication highlights the importance of taking sooting effects into account when calculating steel temperatures in the event of a fire and provides important insights for the application of design rules.<\/p>\n

\u201cThe findings are an important contribution to the realistic design of steel structures in the event of a fire,\u201d emphasizes Dr. Sebastian Moschel, chairman of the IGSB and co-author of the study. \u201cThe influence of sooting should be taken into account in the future, particularly when evaluating hot-dip galvanized steel components exposed to fire. With this study, we are making an important contribution to a better assessment of the thermal boundary conditions in the event of a fire. Our results underline that even seemingly secondary factors such as sooting have a measurable influence on structural fire protection and should not be underestimated.\u201d[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″ offset=”vc_col-xs-12″ css=”.vc_custom_1666258150918{margin-bottom: 0px !important;}”][vc_empty_space height=”15px”][vc_single_image image=”3142″ css=”.vc_custom_1762277107377{margin-bottom: 0px !important;}”][vc_empty_space height=”5px”][vc_column_text]Picture: Test specimens after sooting[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]The complete specialist article is available online at: Einfluss der Verru\u00dfung auf die Emissivit\u00e4t von feuerverzinkten und nicht verzinkten Stahlst\u00fctzenabschnitten\/Influence of Soot formation on the Emissivity of Hot-Dip Galvanized and Non-Galvanized Steel Column Sections – VDI Verlag eLibrary<\/a><\/p>\n
