چکیده
Tuned mass damper inerter (TMDI) is commonly reported to be a lightweight tunable device that can significantly reduce buildings' seismic response. However, the backward action produced by and returned building in conventional TMDIs may either performance or limit potential. This study proposes investigates novel control scheme using large physical ratios generated inerters. Hence, double tuned (DMTDI) formulated. The proposed consists of two TMDs placed at roof connected via an inerter. Thus, transmitted secondary instead building. Both TMDI DMTDI parameters are optimized genetic algorithm (GA). top floor displacement transfer function's H2- norm considered as objective function for minimization. optimally devices then tested under one hundred (100) near far-field ground motions. results obtained show significant response improvement peak displacement, acceleration, base shear. structure energy also investigated; lowest studied observed while scheme.

متن کاملA RELIABILITY APPROACH TO COMPARE OPTIMAL SEISMIC DESIGNS OF MULTIPLE-TUNED-MASS-DAMPER
Passive systems are preferred tools for seismic control of buildings challenged by probabilistic nature of the input excitation. However, other types of uncertainty still exist in parameters of the control device even when optimally tuned. The present work concerns optimal design of multiple-tuned-mass-damper embedded on a shear building by a number of meta-heuristics. They include well-known g...
