Bridges are subject to daily cyclical loads due to frequent use, which can lead to fatigue damage and potential failure. Effective maintenance is important for ensuring the safety of bridges. One way to determine the fatigue environment is by measuring the displacement of materials under cyclic loading. Video cameras are a convenient option for collecting field data, as they can be easily set up. This study utilized a 4K video camera to measure the displacement responses of a bridge.
