Stahlbemessung Teil 4 Querschnittsnachweise
#############################
Video Source: www.youtube.com/watch?v=6vp2dz3UR9I
Im 4. Teil der SOFiSTiK Tutorial Serie schauen wir uns die Querschnittsnachweise an. Es stehen vier Nachweisverfahren zur Verfügung: Vergleichsspannungsnachweis, Lineare Addition der Schnittgrößen (Gl. 6.2), Gesamtinteraktion der Schnittgrößen (Gl. 6.41) und Nichtlineare Spannungen mit Verfestigung (für Querschnittsklasse 4 mit effektiven Breiten nach DIN EN 1993-1-5). Außerdem lässt sich Biegeknicken nach Abschnitt 6.3.1.1 nachweisen. Das ist das Ersatzstabverfahren. Des Weiteren können wir uns vom Programm alternative Querschnitte empfehlen lassen, um eine höhere Ausnutzung zu erzielen. Darüber hinaus findet eine Querschnittsklassifizierung in Klasse 1-4 statt. Der Ausgabeumfang kann reduziert oder erweitert werden.","styleRuns":[{"startIndex":0,"length":727,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"}]},"headerRuns":[{"startIndex":0,"length":727,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"}]}},{"itemSectionRenderer":{"contents":[{"messageRenderer":{"text":{"runs":[{"text":"Comments are turned off.
