When the corridors are soft-connected with damper supports, the seismic performance may be better than rigid connected scheme. To evaluate relative displacement of the damper under server seismic excitation, which is the key problem to prevent collapse of the corridor, theoretical and experimental research are performed. 3-DOF model is established, in which the twin towers and the corridor are represented with 1-DOF respectively. The transfer function and the RMS of relative displacement of damper are deduced in frequency domain. The seismic excitation spectrums include white noise and Kanai-Tajimi spectrum. Parameter study indicates that the resonance between corridor and each tower in vibration frequency will lead to big relative support displacement, that the mass ratio between corridors to tower will decrease the relative support displacement, that the damping ratio of support will decrease the relative support displacement as well. The vibration frequency of corridor should be calculated under restrained of both supports. Experiments of steel frames connected with spring support corridor are performed on dynamic simulator. The test result proves the theoretical conclusion, and indicates that to eliminate the relative support displacement, the adequate damping ration of the corridor should be least.
