dc.description.abstractIntroduction− In this paper, the Real-time Hybrid Simulation (RTHS) of a Non-linear Tuned Mass Damper (NTMD) is described, and compares the results with those obtained from conventional experimental tests of a shear, single-storey structure with the NTMD. Objective− The objetive of this article is to evaluate the effectiveness of an RTHS in estimating the performance of an NTMD. Methodology− The methodology consisted of the following three stages: main structure identification, NTMD design, and experimental evaluation of the structure-NTMD system. For the third stage, RTHS and vibrating table tests were used. Results− The results of the vibrating table tests showed that the NTMD reduced 77% and 63% of the peak accelerations and RMS of the main structure, with respect to the structure without control. The values of these reductions obtained with RTHS were 73% and 63%, respectively. The precision indices of the transfer system corresponded to a generalized amplitude of 1.01 and a delay of 2 ms. Conclusions− The NTMD, with a mass ratio of 10%, achieved reductions of more than 60% of the structural response. RTHS and the vibrating table test demonstrated that the NTMDstructure system had only one peak in frequency response. The noise in the RTHS feedback increased the degree of damping of the controlled structure. Finally, the experimental results demonstrated how RTHS is a technique that effectively predicts the RMS acceleration of the structure-NTMD system and can slightly overestimate its peak acceleration.eng
dc.description.abstractIntroducción− En este artículo se describe la Simulación Híbrida en Tiempo Real (RTHS) de un Amortiguador no Lineal de Masa Sintonizado (NTMD) y se comparan los resultados con los obtenidos de ensayos experimentales convencionales de una estructura a cortante, de un piso, con el NTMD. Objetivo− El objetivo de este artículo es valuar la efectividad de una RTHS para estimar el desempeño de un NTMD. Metodología− La metodología consistió de las siguientes tres etapas: identificación de la estructura principal, diseño del NTMD y evaluación experimental del sistema estructura-NTMD. Para la tercera etapa, se utilizaron RTHS y ensayos sobre mesa vibratoria. Resultados− Los resultados de los ensayos en mesa vibratoria demostraron que el NTMD redujo el 77% y 63% de las aceleraciones pico y RMS de la estructura principal, con respecto a la estructura sin control. Los valores de estas reducciones obtenidos con RTHS fueron 73% y 63%, respectivamente. Los índices de precisión del sistema de transferencia correspondieron a una amplitud generalizada de 1.01 y un retraso de 2 ms. Conclusiones− El NTMD, con una razón de masas del 10%, alcanzó reducciones superiores al 60% de la respuesta estructural. La RTHS y el ensayo de mesa vibratoria demostraron que el sistema estructura-NTMD tuvo solo un pico en la respuesta en frecuencia. El ruido en la retroalimentación de la RTHS aumentó el grado de amortiguamiento de la estructura controlada. Finalmente, los resultados experimentales demostraron como la RTHS es una técnica que predice efectivamente la aceleración RMS del sistema estructura-NTMD y puede sobreestimar ligeramente su aceleración
