Compared with traditional tuned mass damper (TMD), non-traditional (NTMD) has higher damping efficiency in some conditions. Nevertheless, the analytical optimization problem of NTMD not been well solved; especially, multiple optimal solutions are discussed. In this study, closed-form expressions using tuning stiffness derived based on H 2 norm optimization. And vibration mitigation performance is evaluated considering dual-solutions situation subjected to typical ground motion and impulse excitation. Different from solving unique frequency ratio, there exist two sets ratio spring elements for given effective also limited as 1/3. The or isolation robustness optimized far superior lower ratio. larger can be seen an form Maxwell model additional mass. Hence, a large stiffness, namely, design recommended, which different TMD. case adopted when demands practical engineering met parameters small stiffness. compromise scheme provided, combination but less than maximum limit value 1/3 very exceeded 0.5 according engineering.
