Abstract
A detecting device for destructive vibration of structures wherein detected vibration is converted into electric signal and an alarm is actuated when signal amount reaches at least one of a predetermined counting value and integration value is provided. The converted vibration signals are amplified, a high level signal in such amplified signals is detected and amplified by a high level detector, a high level output of this detector is counted by a counter to generate a counter output when the predetermined counting value is reached, a low level signal in the amplified signals is detected and amplified by a low level detector, a low level output of this detector is integrated by an integrating circuit to generate an integration output when the predetermined integration value is reached, and the alarm is actuated whenever at least one of the counter output and integration output is provided.
