Real-time hybrid simulation for tuned mass damper using discrete-time compensation technique
RTHS is a powerful experimental technique which provides engineers the opportunity of performing cost-effective dynamic tests for large or full scale structures.To carry out a successful RTHS test,the time delay and lag need to be reduced by an appropriately designed compensator.Previously,the authors have developed an optimal discrete-time feedforward compensator,namely finite impulse response(FIR)compensator,and successfully applied it in RTHS.In this study,this technique has been applied to study the behavior of a Tuned Mass Damper.As an effective damping technique,Tuned Mass Damper(TMD)has been successfully applied in many civil engineering applications,such as structural vibration response reduction under wind and earthquake excitations.In this study,a real-time hybrid simulation(RTHS)test is performed by using the integrated compensator,to evaluate the response reduction effect of a TMD.The TMD is assumed to be installed in a two-story reinforced concrete frame building.The dynamic excitations that have been considered in this study include both earthquake and wind loads.The compensation performance of the FIR compensator is evaluated.In addition,the response metrics related to both the maximum and root-mean-square(RMS)of the displacement response,are also calculated using the obtained RTHS results to evaluate the response reduction effects.
