Digital twin based lifecycle modeling and state evaluation of cable-stayed bridges

Research progress and prospect of digital twin in bridge engineering

“…For example, a digital twin of a real machine can be built on a cloud platform and use the collected data and existing knowledge to simulate health conditions (Lee et al, 2013). Despite these advancements, research on digital twin was still relatively limited, and application development was hindered (Lu and Brilakis, 2019) 101 Automation in construction E (Broo et al, 2022) 18 Automation in construction F, E (Pregnolato et al, 2022) 9 Automation in construction F (Song et al, 2023) 3 Automation in construction F (Yang et al, 2022) 2 Automation in construction E (Pantoja-Rosero et al, 2023) 1 Automation in construction E (Gao et al, 2023) -Automation in construction F, O&M (Bittencourt et al, 2021) 1 Proceedings of the 10th international conference on bridge maintenance, safety and management, IABMAS 2020 F, O&M (Lai et al, 2022) 4 Case studies in construction materials O&M (Lu et al, 2020) 1 Construction research congress 2020 E (Febrianto et al, 2022) 3 Data-centric engineering E (Sánchez-Rodríguez et al, 2020) 6 EG-ICE 2020 workshop on intelligent computing in engineering, proceedings E (Jiang et al, 2021b) 28 Engineering structures O&M (Guo and Fang, 2023) -Engineering with computers E (Broo and Schooling, 2021) 11 IEEE access F (Dang et al, 2022) 22 IEEE transactions on industrial informatics F, O&M (Dan et al, 2021) 12 IEEE transactions on intelligent transportation systems F, O&M (Shim et al, 2019b) 15 International conference on smart infrastructure and construction 2019 O&M (Van Nimmen et al, 2021) 7 Journal of bridge engineering O&M (Omer et al, 2021) 7 Journal of bridge engineering E, O&M (Zhao et al, 2022) 7 Journal of bridge engineering O&M (Ye et al, 2020b) 26 Journal of civil structural health monitoring O&M (Baisthakur and Chakraborty, 2021) 7…”

“…Currently, bridge digital twins are modeled in a variety of ways and also at discrete and smaller time scales. For example, digital twin models of bridges in the design phase are represented directly in computer-aided design (CAD) models (Guo and Fang, 2023). The geometric digital twin (gDT), which reflects the variation of real bridge geometric features, and the numerical digital twin (nDT), which simulates the real structural behaviour and performs simulation analysis, are the more mentioned ones.…”

Towards a Comprehensive Damage Identification of Structures though Populations of Competing Models

“…This is primarily due to the large computational burden of numerical models of real-world civil engineering structures, as well as the considerable volume of model evaluations required by global optimization algorithms. As a solution to reconcile St-Id with real-time SHM schemes, a large variety of surrogate models (SM) have been reported in the literature to bypass resourceful numerical models in a computationally efficient way [31][32][33]. In this light, Cabboi et al [34] adopted a second-order response surface model to metamodel the modal predictions of a 3D FEM of a stone-masonry tower, the San Vittore bell-tower in Varese, Italy.…”
