Abstract
Analyses and a discussion of the consequences for lightweight structures, typical wood frame or truss structures, when a change of the statistical description of random parameters in a reliability based code format is made without considering how the code once was derived is presented. The special case when the statistical description of variable load is altered, is described with and without considering the origin of the current safety indices.
Zusammenfassung
Analysen und eine Diskussion der Konsequenzen für leichte Konstruktionen, typische Holzrahmen oder Dachstühle werden präsentiert, bei Veränderung der statistischen Beschreibung von Zufallsparametern in einem auf Verläßlichkeit basierenden Kodierungsformat, ohne zu berücksichtigen, wie der Kode früher abgeleitet wurde. Der spezielle Fall, wenn die statistische Beschreibung der variablen Belastung verändert wird, wird mit und ohne Berücksichtigung des Ursprungs der aktuellen Sicherheitsindices beschrieben.
