Abstract

In this paper, lateral loading tests were conducted on a full-scale RC partial wall with a shear span ratio of 0.5, and the relationship between the area of concrete spalling or loss and the chord rotation was derived from test results. Furthermore, the pre-trained DNN model was fine-tuned to generate a detector that can accurately detect and measure the concrete spalling and loss on the painted surface of RC partial walls. Finally, it was confirmed that both of them can be used to evaluate the experienced chord rotation from seismic damage photographs of RC partial walls.
