Structural Systems
Japanese version is here (OLD) and here (NEW).
Analysis and design of ship and offshore structures related to a
buckling/plastic collapse strength of structural members and systems are
the major research areas at this laboratory. Primary attentions have been
focussed on the buckling/plastic collapse behaviour of continuous
stiffened plating considering initial welding imperfections and
plate/stiffener interactions, ultimate limit state formulation of
structural members and systems and its application to the reliability-based
safety assessment and structural optimization, and the development of
efficient computational model for the nonlinear structural analysis of
large structural systems. Several interconnected workstation computers
and testing facilities are available for the educational and research
activities. The current research subjects are:
- Progressive collapse analysis of ship hull girder under longitudinal bending and shear
- Development of efficient computational model (Idealized Structural Unit)
for the buckling/plastic collapse analysis of stiffened plate structures
considering initial imperfections and plate/stiffener interactions
- Buckling/plastic collapse behaviour of plates and stiffened plates under
cyclic load
- Buckling of stiffened composite panel accompanied by delamination and
debonding
- Sensitivity analysis and reanalysis of nonlinear response of structures
- Reliability analysis and optimization of stiffened plate structures
- Structural analysis and design of Very Large Floating Structures in waves
