Abstract: Based on the China Beijing–Hangzhou Grand Canal Museum project, this study addresses the challenge that no existing manufacturer, domestically or internationally, could provide an off-the-shelf product meeting the safety and stability requirements for the first large-scale application of LIULI to a building curtain wall. Without a proven solution, the installation faced severe risks including physical damage, spontaneous fracture and falling debris, and dislodgement due to the substantial self-weight. Therefore, a design and performance study of large-scale corrugated three-dimensional LIULI composite panels was conducted. The final design adopts adhesive bonding of a double-layer heat-strengthened glass backing to a large-format, heavy corrugated 3D LIULI slab measuring 2.5m², 350kg, with a gradient thickness of 45–130mm. After comprehensive evaluation, a modified enhanced ethylene-vinyl acetate copolymer (PVE) interlayer was selected for lamination. The resulting structural configuration is defined as: LIULI slab + 2.28mm PVE + 10mm heat-strengthened glass + 1.52mm PVE + 10mm heat-strengthened glass. This composite system ensures high safety and high stability for large-scale corrugated 3D LIULI architectural applications.
