Resonance detection method and system for steel structure building

The invention provides a resonance detection method and system for a steel structure building. The detection method comprises the following steps: installing a vibration sensor at a preset position in a to-be-detected steel structure building; installing a vibration sensor at a vibration source around the to-be-tested steel structure building; synchronously acquiring first vibration data of the to-be-tested steel structure building and second vibration data of the vibration source; and comparing the first vibration data with the second vibration data of the plurality of vibration sources, and determining a resonance source causing resonance of the to-be-tested steel structure building from the plurality of vibration sources according to a comparison result. By the adoption of the technical scheme, the resonance source causing resonance of the steel structure building can be accurately detected, so that a user can solve the resonance problem of the steel structure building in the mode that the resonance source
