Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 11, Page 1659-1675, 1 June 2024.Abstract Digital twin requires establishing a self‐updated model to simulate the structural damage perceived onsite. Despite the great success in damage identification and quantification, the difficulty in registration still limits the efficiency of model updating.
