THE APPLICATION OF SHAKEDOWN THEORY TO THE DESIGN OF BRIDGE SUPERSTRUCTURES. ACMSM 9; THE NINTH AUSTRALASIAN CONFERENCE ON THE MECHANICS OF STRUCTURES AND MATERIALS, 29-31 AUGUST 1984, UNIVERSITY OF SYDNEY

Although the limit states of incremental collapse and alternating plasticity are more appropriate than the static collapse limit state for moving structures or structures with moving loads, acceptance in practice is slow, partly through lack of understanding and partly through computational difficulty. It is shown how grids, plates and composite structures are accessible to reasonably accurate upper bound analysis using perceived collapse mechanisms, without resort to mathematical programming, and using the elastic analysis envelope of structural actions as a base (Author/TRRL)
