Structural damage was simulated by loosening the bolts at the beam-to-girder connections.
The dataset provided here consists of 31 structural scenarios:
The first scenario corresponds to the reference (undamaged) case.
In scenarios 2 to 31, damage was introduced to the joints 1 to 30, respectively. The joint numbers are shown in the picture below.
Location of the damaged joint for scenarios 1 to 31.
