Large-scale landmark art venue decoration projects are characterized by ultra-short construction periods,large volumes,complex spaces,and multiple special-shaped surfaces.Addressing the super-large-scale,inner and outer double-layer,8K finish,and special-shaped hyperbolic mirror seamless stainless steel decorative facade components that cover the indoor flying escalators of such venues,a digital construction technique for the self-bearing facade system is proposed.Finite element numerical simulation is used to develop the structural optimization design for the flying escalator facade system,ensuring project timelines while avoiding resonance issues.Special-shaped hyperbolic mirror stainless steel panels are optimized for single curvature,enhancing processing efficiency.Industrialized processing,digital disassembly,modular pre-assembly,and overall industrial lifting techniques are employed to achieve a seamless mirror stainless steel finish.This digital construction solution promotes the application of digital techniques in constructing special-shaped components for large-scale venue decoration,improving design,processing,installation efficiency,and construction quality.
