“…Moreover, there is growing interest in creating nDT directly from as-is models for structural analysis. Shu et al (2019) conducted linear finite element analysis using 3D point cloud data, focusing on bridge structural performance. However, The point cloud focuses more on the appearance of the bridge structure and does not consider the degradation of material properties over time.…”

“…On the other hand, finite element model updating, as a digital twin technique (Ye et al, 2020a), is widely used to create the nDT of bridges for real-time analysis, prediction, and simulation. Although numerical models for structural analysis can be directly generated from the gDT of bridges, the accuracy and real-time capability of nDT created using this method require improvement (Shu et al, 2019). An alternative approach to creating the nDT involves updating structural parameters using Bayesian inference methods and monitoring response data (Febrianto et al, 2022; Ghahari et al, 2022).…”

Intelligent Prediction Method for Operation and Maintenance Safety of Prestressed Steel Structure Based on Digital Twin Technology

“…As a key concept to solve the problem of Information Physics integration, digital twin has been widely concerned and studied by the academic community, and this concept has been gradually applied in the construction industry. Shu et al [19] provided faster and more accurate procedures to capture the spatial information required by a digital twin of a concrete structure using 3D point cloud data. Zandi et al [20] propose a framework for the digital twin of infrastructure.…”
