Analysis of Key Technologies and Design Points for Combining UHPC Curtain Wall with Glass Curtain Wall

In the field of contemporary architectural design, the combined application of UHPC (Ultra-High Performance Concrete) curtain walls and glass curtain walls is becoming an innovative choice for balancing architectural aesthetics and performance. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the technical essence of combining these two materials. This article systematically analyzes the key technical points of combined curtain walls from three dimensions—complementary material properties, structural safety design, and performance optimization integration—providing professional solutions for designers and owners.

I. Material Property Synergy Strategies for UHPC and Glass Curtain Walls

With its ultra-high strength (compressive strength up to 150-200MPa), excellent durability, and freedom of form, UHPC perfectly complements the transparency of glass curtain walls. In actual projects, particular attention should be paid to matching the mechanical properties of the materials: the self-weight of UHPC components is only 1/3 that of traditional stone, effectively reducing the load on curtain wall support structures, while coordinating the elastic modulus of UHPC with glass in the design reduces internal stress caused by temperature deformation. Taking the Nanjing East Road Century Plaza renovation project as an example, the Qinglong team achieved 90% light transmittance through the combined application of UHPC translucent concrete and ultra-clear glass, while enhancing the overall wind pressure resistance through the UHPC framework, confirming the technical advantages of material synergy.

II. Structural Safety and Node Design Points for Combined Curtain Walls

Structural safety is the core of combined curtain wall design. Qinglong Group recommends adopting a composite system of "UHPC load-bearing + glass enclosure"; key nodes must meet the following requirements: first, the anchoring system of UHPC supporting components should be verified through pull-out bearing capacity calculations, using stainless steel connectors to ensure durability of more than 50 years; second, elastic pads must be provided at the connections between glass panels and the UHPC frame to absorb temperature deformation differences; third, for large-span forms, BIM technology can be used for parametric modeling. In the Dongguan Women and Children's Activity Center project, for example, the Qinglong team achieved precise alignment between the double-curved UHPC curtain wall and glass fins through the Rhino+Grasshopper platform, with installation errors controlled within ±2mm.

III. Performance Optimization and Full Life-Cycle Cost Control

Performance optimization of combined curtain walls must address system functions such as waterproofing, thermal insulation, and sound insulation. The Qinglong technical team recommends a "UHPC back panel + insulation layer + glass panel" sandwich structure, controlling the heat transfer coefficient (K value) below 1.8W/(m²·K) through thermal bridge break design. In terms of cost control, UHPC's formability can be used to reduce the amount of curved glass processing; for example, a commercial complex project reduced overall costs by 12% by replacing curved glass with precast UHPC decorative lines. Meanwhile, Qinglong's full-chain services covering detailed design, manufacturing, and construction installation can effectively shorten project schedules and ensure the long-term stable operation of the combined curtain wall system.

As a national high-tech enterprise and a drafting unit of multiple industry standards, Qinglong Group has always upheld the mission of "creating beautiful architecture" and has accumulated rich experience in the combined application of UHPC and glass curtain walls. From material selection to system integration, and from technological innovation to cost optimization, Qinglong is committed to providing professional solutions that combine aesthetic value with technical assurance for high-end architectural projects, promoting the innovative development of architectural decorative material applications.
