Three velocity pulse-likes developed by Nicos Makris are employed to simulate Near-Fault earthquake. The vibration control effectiveness are extensively investigated through the comparison of response spectrum, response time history, and the energy dissipation time history of the structure with and without MTMDs. Numerical studies show that although the passive MTMD could not reduce the maximum response in the pulse duration significantly, but the structural response decay quickly after impulse. According to various types of impulses, it can be observed that the more cycles of pulse, the more useful for MTMDs to reduce the peak structural response. From the viewpoint of energy dissipation, it is also found that structural damage can significantly eliminated because most earthquake energy is dissipated by MTMDs and the rate of energy dissipation is much faster than those of structures without MTMDs.
