Damage Detection of Bridges under Environmental Temperature Changes Using a Hybrid Method

Damage Detection of Bridges under Environmental Temperature Changes Using a Hybrid Method

Principal component analysis (PCA)-based method is popular for detecting the damage of bridges under varying environmental temperatures. However, this method deletes some information when the damage features are projected in the direction of nonprincipal components; thus, the effectiveness of PCA-ba...
