Das zweidimensionale Rahmensystem wird mit einer Punktlast in A belastet. Durch Erhöhung der Punktlast verformt sich das System zunehmend bis Stabilitätsprobleme auftreten. Ziel des Beispiels ist es, das Last-Verformungs-Verhalten des Systems bis zum Erreichen des Knickpunkts zu berechnen. Verformungen sind nur in der XY-Ebene möglich.

Material: linear-elastisch; E-Modul = 71740 MPa; Querdehnzahl = 0.0

Lagerung: ux = uy = 0 in B und C

Belastung: P = 1.0 kN
