Damage Identification of a Derrick Steel Structure Based on the HHT Marginal Spectrum Amplitude Curvature Difference
Damage experimental conditions of the derrick steel structure.
|Condition||Damage form||Damage type||Damage position|
|1||Pin loose||Single damage||The place between second segment and third segment|
|2||Single damage||The place between third segment and forth segment|
|3||Double damage||Integrating the first two kinds of damage location|
