Probabilistic analysis of the Stussi-Kollbrunner paradox

In most text books on Plasticity Theory a reference is made to the famous tests performed by Stiissi and Kollbrunner in 1935. The test object was a continuous beam on four supports, loaded by a concentrated point load halfway the central span. According to a straight forward application of the theory of plasticity the load carrying capacity of...

Lower Bound Approximation for Elastic Buckling Loads

An approximate method for the elastic buckling analysis of two-dimensional frames is introduced. The method can conveniently be explained with reference to a physical interpretation: In the frame every member is replaced by two new members: - a flexural member without extensional rigidity to transmit the shear force and the bending moments; - a...
