Dipl.-Ing. Peter Osterrieder and Professor Dr.-Ing. Ekkehard Ramm

For the analysis of two-dimensional, unbraced systems using second order plastic theory two methods expanding on approaches used in the elastic range are offered:

a) combined force and displacement method (M-ϑ method),
b) displacement method.
