Die Temperatur nur wenige Zentimeter im Inneren des Holzbalkens betr\u00e4gt lediglich 40 \u00b0C, w\u00e4hrend sie au\u00dfen fast 1000 \u00b0C erreicht.\nFeuer und Hitze ver\u00e4ndern die mechanische Festigkeit nicht. Ein Einsturz tritt ein, wenn die Verbrennung den verbleibenden Querschnitt so stark verkleinert, dass dieser seine tragende Funktion nicht mehr erf\u00fcllen kann. Die Lebensdauer ist proportional zur Dicke des Querschnitts, weshalb hohe Belastungen und Festigkeiten nur durch eine \u00dcberdimensionierung des Balkens aufrechterhalten werden k\u00f6nnen, ohne dass Behandlungen mit intumeszierenden oder feuerhemmenden Lacken, Putz oder Kalziumsilikatplatten erforderlich sind.   \t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<div class=\"swiper-slide\" data-slide=\"2\" role=\"group\" aria-roledescription=\"slide\" aria-label=\"2 von 3\">\n\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-85d1d61 e-flex e-con-boxed e-con e-child\" data-id=\"85d1d61\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-85d6bfb elementor-widget elementor-widget-image\" data-id=\"85d6bfb\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2026\/06\/GFK-Website-Firewall_2026-26-150x150.webp\" class=\"attachment-thumbnail size-thumbnail wp-image-17090\" alt=\"\" srcset=\"https:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2026\/06\/GFK-Website-Firewall_2026-26-150x150.webp 150w, https:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2026\/06\/GFK-Website-Firewall_2026-26-300x300.webp 300w, https:\/\/www.vernicifirewall.it\/wp-content\/uploads\/2026\/06\/GFK-Website-Firewall_2026-26.webp 401w\" sizes=\"(max-width: 150px) 100vw, 150px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-cb73e25 elementor-widget elementor-widget-heading\" data-id=\"cb73e25\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">STAHL<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d998488 elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"d998488\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\tStahl gilt als nicht brennbarer Werkstoff, was durchaus zutrifft, aber er ist auch ein hervorragender W\u00e4rmeleiter. Bei einem drastischen Temperaturanstieg, wie er beispielsweise bei einem Brand auftritt, verliert Stahl rasch seine Stabilit\u00e4t. \nNach nur 5 Minuten Einwirkung von Feuer erreicht der Stahl etwa 500 \u00b0C. Dies ist die sogenannte kritische Temperatur f\u00fcr dieses Material. Nach 10 Minuten Branddauer gibt die Stahlkonstruktion nach und st\u00fcrzt wie ein Kartenhaus in sich zusammen. Stahl dehnt sich um etwa 0,012 mm pro Meter L\u00e4nge und Temperaturgrad aus. Das bedeutet bei einer Temperatur von 500 \u00b0C eine Dehnung von 6 mm pro Meter.

Die W\u00e4rmeleitf\u00e4higkeit von Beton betr\u00e4gt 2,1 W\/mk, gegen\u00fcber 60 W\/mK bei Stahl \u2013 ein Faktor, der bei Bauteilen aus Stahlbeton und insbesondere aus vorgespanntem Beton nicht zu vernachl\u00e4ssigen ist.\nKalksteinzuschlagstoffe weisen keine nennenswerten Einbu\u00dfen an mechanischer Festigkeit auf, es sei denn bei Temperaturen \u00fcber 750 \u00b0C, bei denen die thermische Zersetzung des Kalksteins in Kalk und Kohlendioxid beginnt. Das Problem ist der darin enthaltene Stahl, und von entscheidender Bedeutung ist der thermische Schutz der Beton\u00fcberdeckung. Tats\u00e4chlich spielen hohe Temperaturen in Stahlbetonkonstruktionen vor allem in Bezug auf den Stahl eine wesentliche Rolle, der bei Temperaturen \u00fcber 500 \u00b0C einen Gro\u00dfteil seiner Eigenschaften verliert.\nDiese Schwachstellen werden zu bevorzugten Kan\u00e4len f\u00fcr den W\u00e4rmefluss, der einen lokalen Temperaturanstieg verursachen kann, der innerhalb k\u00fcrzester Zeit 500 \u00b0C \u00fcbersteigen kann. Auch in diesem Fall \u00e4hnelt das Brandverhalten dem eines Stahltr\u00e4gers, weshalb der Einsatz von intumeszierenden Farben oder anderen Schutzma\u00dfnahmen vorgeschrieben ist.
