✦ Synopsis


Shakedown of planar beam structures\ with possible di}erent reinforcements in the upper and lower layers of the beam members\ subjected to quasi!statically as well as dynamically ~uctuating loads is studied[ With an assumption of elastic perfectly!plastic behaviour of the beams in bending\ a reduced kinematic formulation for the safety factor determining shakedown limits is constructed\ which is proved to be equivalent to "but simpler than# the original one\ and ready for use in solving practical problems[ Þ 0887 Elsevier Science Ltd[ All rights reserved[

This paper uses theorem of shakedown to assess the shakedown limit of elastic-plastic offshore structures. For this aim, an envelope of elastic response of the structure to cyclic loading cases is required. The shakedown limit is basically a valid collapse mechanism and can be quantified using yield

Problems from plastic analysis are based on the convex, linear or linearised yield/strength condition and the linear equilibrium equation for the stress (state) vector. In practice one has to take into account stochastic variations of several model parameters. Hence, in order to get robust maximum l
