EVALUATION DEVICE OF VIBRATION SERVICEABILITY OF BRIDGE

摘要

A bridge vibration usability evaluation device is disclosed. The bridge vibration usability evaluation apparatus includes a table placed on the ground; A linear transfer device installed on the table; Image measurement for photographing a target area, which is a partial area under the upper structure of the bridge that is selected when photographing the upper structure of the bridge, for a predetermined time, which is mounted on the linear transfer device and can move in the horizontal and vertical directions. Device; A bridge natural frequency measurement system for measuring the vertical displacement of the target area for each time period in the image captured and stored by the image measuring device, and for measuring the natural frequency of the bridge based on the measured vertical displacement of the target area for each time period; And a control unit for controlling the linear transfer device, the image measurement device, and the bridge natural frequency measurement system.
