SEISMIC RESPONSE REDUCTION OF STRUCTURES USING OPTIMUM ABSORBER PARAMETERS

摘要：

The effectiveness of the Tuned Mass Dampers (TMD) depends on the proper tuning of the characteristics of TMD to that of the structure and structures with different time period respond to same earthquake in different manner. From the literature it can be seen that no procedure has been carried out to optimize the mass ratio (μ) and the procedures adopted to optimize frequency ratio (α) and damping ratio of the TMD (γ) for the given μ, uses values of μ which may be too high for practical implementations. Hence this paper presents a procedure for optimization of parameters, μ, α and γ of TMD subjected to seismic excitation. The procedure has been validated using 20 earthquake records using the lumped- spring mass system.
