In a groundbreaking development for the construction industry, researchers have successfully applied rotation lifting technology to large-span spatial grid structures, significantly reducing the height of assembly scaffolding and high-altitude work. This innovation, detailed in a recent study published in *Jianzhu Gangjiegou Jinzhan* (translated as *Advances in Structural Engineering*), promises to revolutionize the way large-scale structures are built, with profound implications for the energy sector and beyond.
The study, led by Dai Junhui, delves into the numerical simulation of the entire construction process of a large-span spatial grid structure using rotation lifting technology. By optimizing the rotation angle and employing reverse analysis, the researchers were able to determine the optimal assembly position of the structure. “Through reverse analysis, we can effectively avoid rigid body displacement when the structure is detached from the scaffolding,” Dai Junhui explained. This precision is crucial for ensuring the safety and efficiency of construction projects.
The research team conducted a comprehensive analysis of the structure’s rotation and lifting process, from detachment to reaching the design elevation. Their findings revealed that the numerical analysis results closely matched the actual measured values, validating the effectiveness of their approach. “Our numerical analysis method can accurately simulate the entire process of rotation lifting for steel structures, providing valuable insights for precise construction control,” Dai Junhui added.
The implications of this research are far-reaching, particularly for the energy sector. Large-span spatial grid structures are often used in the construction of energy facilities, such as power plants and renewable energy installations. By reducing the need for high-altitude work and minimizing the height of assembly scaffolding, this technology can enhance safety, reduce costs, and improve construction efficiency. “This innovation has the potential to transform the way we build large-scale energy infrastructure, making the process safer, more efficient, and more cost-effective,” said an industry expert familiar with the research.
As the construction industry continues to evolve, the integration of advanced technologies like rotation lifting will play a pivotal role in shaping the future of infrastructure development. The study by Dai Junhui and his team represents a significant step forward in this direction, offering a glimpse into the possibilities that lie ahead. With the detailed analysis and validation provided in their research, the construction industry is poised to embrace this innovative approach, paving the way for safer, more efficient, and more sustainable construction practices.
