Advances in construction technology result in increased complexity and multi-functionality of modern buildings and structures. This is especially true for unique structures with large spans and heights. Based on the current standards, such structures must be monitored as well as the stress-strain state (SSS) of supporting structures. In addition, the SSS must be continuously checked during operation. Indeed, facilities of higher complexity are more prone to errors or discrepancies, which can reduce the reliability of some structures as well as the whole system. This can be caused by human factor, variability of external and internal forces and impacts, specifics of erection and installation, and many other reasons. Therefore, unique buildings and structures must be built with monitoring systems or operated under routine inspection. This way we can determine if the behavior of the erected structure complies with the standards and regulations.

The construction of cable net structures is intricate, and the construction process itself is laborious. Conventional safety control measures during the construction of cable net structures involve monitoring cable forces and deformations at specific moments during the construction steps. However, these measures do not guarantee adequate safety assurance. This paper proposes a method for the safety control of cable net structures, considering spatiotemporal changes, based on the concept of digital twins. This method enables real-time monitoring and control of the cable net construction process onsite, facilitating a comparative analysis between the mechanical and geometric information of the construction site and the real-time finite element simulation results. Such an approach ensures safety control throughout the construction process. Firstly, a twin model framework for safety control is established. Then, the methods for spatiotemporal representation, data collection, and processing at the construction site are analyzed. Finally, the proposed method is validated through its application to the Xiaotian Cultural and Sports Park project. The results demonstrate that this method can achieve real-time monitoring and control of cable net structure construction.
