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 patternsDescription

1The braces in the first story have all lost their stiffness.
2The braces in the first and third stories have all lost their stiffness.
3The north brace on the west face of the building, located in the first story, has lost its stiffness.
4The 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.
5In 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.
6The north brace on the west face located in the first story has lost one-third of its stiffness.
