Special Issue Information

Dear Colleagues,

The design and construction of lightweight and large-span buildings demand creative structural forms and sophisticated computational methods to achieve efficiency, functionality, and aesthetic appeal. This Special Issue focuses on advancing the knowledge and application of innovative structural solutions for large-span architectural and engineering projects. Key topics include (but are not limited to) new structural systems and components, new numerical computational methods for structure complex behavior analysis, new design methods using optimization strategies and AI-based generative algorithms, robotically assisted construction and deconstruction, and intelligent maintenance.

We welcome contributions that present original research, case studies, or reviews promoting the latest developments in this dynamic field. Of particular interest are methodologies that integrate advanced computational techniques, simulation technologies, and real-world applications. This Special Issue aims to provide a platform for academics, researchers, and professionals to share knowledge, inspire future advancements, and foster a deeper understanding of how innovative structural and computational strategies can reshape the possibilities for lightweight and large-span buildings.

This study introduces a multi-point optical flow cable force measurement method based on Euler motion amplification to address challenges in accurately measuring cable displacement under small displacement conditions and mitigating background interference in complex environments. The proposed method combines phase-based magnification with an optical flow method to enhance small displacement features and improve SNR (signal-to-noise ratio) in cable displacement tracking. By leveraging magnified motion data and integrating auxiliary feature points, the approach compensates for equipment-induced vibrations and background noise, allowing for precise cable displacement measurement and the identification of vibration modes. The methodology was validated using a scaled model of a cable net structure. The results demonstrate the method’s effectiveness, achieving a significantly higher SNR (e.g., from 7.5 dB to 22.24 dB) compared to traditional optical flow techniques. Vibration frequency errors were reduced from 6.2% to 1.5%, and cable force errors decreased from 11.38% to 3.13%. The multi-point optical flow cable force measurement method based on Euler motion magnification provides a practical and reliable solution for non-contact cable force measurement, offering potential applications in structural health monitoring and the maintenance of bridges and high-altitude structures.
