Study on Suspended Mass Pendulums for Vibration Control of Transmission Tower under Seismic Excitation

Article Preview

Abstract:

In order to research the effectiveness of passive control on transmission tower vibration control under seismic excitation, suspended mass pendulum (SMP) is carried out in this study. Based on the mechanism and equation of earthquake vibration control, earthquake induced vibration control for transmission tower model with suspended mass pendulums was performed by using numerical simulation. Using SAP2000 software, three-dimensional finite element model of a transmission tower is created, and seismic records are selected by different site soils. Typical time history curves and the maximum responses of displacement, axis force, shear force and moment of the transmission tower without and with suspended mass pendulums are obtained by numerical simulation analysis. The results show that the SMP is very effective in mitigating tower vibration, and the method can be a reference for practice engineering application.
