Unsupervised Structural Damage Detection Technique Based on a Deep Convolutional Autoencoder
Table 1
Description of the damage patterns considered for IASC-ASCE benchmark structure [37].
Damage patterns
Description
1
The braces in the first story have all lost their stiffness.
2
The braces in the first and third stories have all lost their stiffness.
3
The north brace on the west face of the building, located in the first story, has lost its stiffness.
4
The north brace on the west face located in the first story and the west brace on the north face located in the third story have lost their stiffness.
5
In addition to damage in pattern (4), the beam-column connection noted in Figure 6 is partially unscrewed and thus can only transfer forces and does not sustain any bending moments.
6
The north brace on the west face located in the first story has lost one-third of its stiffness.
