Outline of Final Research Achievements

The robust optimal design methodology for the vibration control structure has been proposed to control the structural seismic response under various structural uncertainties, e.g. construction error, deterioration, variability of material property, etc. Compared with conventional optimal structural design scheme, the proposed robust optimal design method is effective for the worst scenario which can be hard to consider in the general structural design procedure. The supremum of the design criteria can be investigated in the robust design under various uncertainties in design process, which can enhance the reliability of structural safety of the building.
