Fachtagung Baustatik - Baupraxis, 2024https://tore.tuhh.de/handle/11420/53739Numerous reviews of digital twins have been reported in recent years. However, the majority of digital twin (DT) reviews within the field of civil engineering primarily examine DT implementations tailored to specific projects or investigate particular application domains in civil engineering. DT architectures, including layers and components, have received minimal consideration until now. This study conducts a systematic literature review (SLR) of digital twins to establish a scientific basis on digital twins in civil engineering, aiming to reach a reference DT architecture that includes layers and components. The SLR is conducted for peer-reviewed, indexed literature of existing DT architectures to propose the reference DT architecture. The reference DT architecture serves as a blueprint for implementing DT applications in civil engineering, providing a common understanding and strengthening the reliability of digital twins in civil engineering.enTechnology::600: TechnologyConference Paper10.15480/882.9247Conference Paper
