Verschiebungsplan

Beitragvon Heidelmann am So 4. Mai 2014, 17:37

Moin,
Für das Fachwerk soll die Verschiebung des Punktes C bestimmt werden und zwar mit dem Verschiebungsplan.

(Stäbe von links aus: 1,2,3)

Ich hab jetzt erstmal 2 Gleichungen für die Stabkräfte aufgestellt:

S1 (2^-1/2) - S3 = 0

S1(2^-1/2) + S2 + F = 0

Als weitere Gleichung müsste ich jetzt Verhältnisse zwischen den Stablängenänderungen bilden. Nur weiss ich nicht wie. Habt Ihr ne Idee ?
