Abstract：With the random decrement method (RDM), the non-forced vibration responses are extracted from the galloping responses of a transmission line, and the galloping frequencies, vibration modes and damping ratios are identified by the eigensystem realization algorithm (ERA) with input of the free vibration responses. The identification software is coded with Matlab, which is proved by the test of beam vibration. Further, by means of the developed software, the frequencies, vibration modes and damping of the real six bundle conductor lines are identified. The method and software provide an important means for the identification of galloping characteristics of real transmission lines.
