Principles and optimal design methods for large ship grillages
Г.Б. Крыжевич, E. Norkov, A. Filatov
Abstract
Based on the previously developed approach to structural ship design, the authors optimize a large-span deck grillage taking into account several design loading scenarios. Topological optimization made it possible to find an optimal structural layout of the grillage, and parametric optimization yielded the scantlings of beams and simultaneously reduced grillage weight. Additional gain in structural weight was achieved by means of the openings in beam webs.
