Research on Digital Twin Framework Based on Monitoring Data and Dynamic Characteristics Assessment of Super High Steel Residential Buildings
摘要
With the increasing market demand for ultimate architectural space in high-end residential buildings and diversified flexible layouts, Super High Steel Residential Buildings are being increasingly applied in residential construction. Due to their lightweight materials, lower self-weight, and relatively relaxed deformation requirements, Super High Steel Residential Buildings exhibit greater flexibility compared to concrete structures of the same height. Consequently, they are more susceptible to significant horizontal vibrations under wind load excitation. Due to construction errors, material differences, and variations in boundary conditions, there are often significant discrepancies between the actual built structure and the design analysis results. To more accurately capture the key structural dynamic characteristics influencing wind-induced vibrations, structural monitoring is introduced during both the construction and operational phases. Meanwhile, a digital twin framework based on monitoring data is established, enabling real-time integration between the physical building and the virtual model. This provides an efficient monitoring and optimization tool for the design, construction, and operation of buildings. Taking a Super High Steel Residential Building in a coastal region as an example, this paper introduces the various layers and functions of the digital twin framework, demonstrating how it integrates with structural monitoring data. It explores the changes in structural dynamic characteristics at different construction stages based on monitoring data and compares them with the analysis results from the design phase to identify the causes of discrepancies. Furthermore, the study evaluates the wind-induced vibration comfort of the structure under typhoon conditions during the construction phase based on monitoring data.
