In order to grasp the vortex-induced vibration characteristics of large-span pedestrian suspension bridge （glass deck）， a vortex-induced vibration wind tunnel test was conducted for the girder section model of the bridge， The influence rule of wind attach angle， damping ratio， deck roughness， railing setting on its vortex-induced vibration performance was studied. The results show that with the wind attach angles changing from positive to negative， the amplitude of vertical and torsional vortex-induced vibration increases. Meanwhile， the lock-in region of wind speed of vertical vortex-induced vibration is basically unchanged， but the torsional vortex vibration shifts to a low wind speed region. Improving damping ratio can obviously restrain the vortex-induced vibration， and the restrain effect of torsional vortex vibration is more significant， while it has little effect on the lock-in region of wind speed. With the decrease of deck roughness， the amplitude of vertical and torsional vortex-induced vibration increases. Therefore， using glass deck can degrade the performance of vortex-induced vibration. Both setting up airflow-suppressing board on railing and closing railing interval can improve the performance of vortex-induced vibration. Considering the construction convenience， closing railing interval is more practical.
