Abstract:A minimum volume multicriterion design of
elastic perfectly plastic steel frames subjected to a combination of quasi-static fixed and cyclic loads, bounding the transient phase plastic deformations, is proposed. The
problem is formulated according to a plastic shakedown criterion, so that incremental and instantaneous collapse are certainly prevented when the frame is subjected to very strongly
amplified cyclic loads. The further condition that the structure must also behave elastically in serviceability condi… Show more
