| Outline of Final Research Achievements |
This study focuses primarily on corrugated steel plates, steel plate sandwich panels, and cold-formed channel section members to evaluate their stability and seismic performance.
These evaluations confirmed the properties of the materials constituting the members, and specified the relationship of the material properties of the members with the structural properties. Performing theoretical analysis, numerical analysis, and loading test clarified the structural properties of the members according to boundary conditions, connection conditions, and loading conditions of the members. Moreover, a performance evaluation formula was derived that would contribute to rational design methods.
A structural form by appropriately combining thin plate members was proposed and showed the future development and potential of the thin plate structure type through trial construction experiment.
