Analysis of Key Technologies and Design Points to Note When Combining UHPC Curtain Walls with Glass Curtain Walls

When architectural aesthetics meet material technology, the combined application of UHPC curtain walls and glass curtain walls is becoming the golden pairing of modern building envelope design. As an industry leader with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group draws on its full-chain service experience to decode the technical secrets of this combined system for designers and owners, enabling buildings to achieve a perfect balance of function and art amid the interplay of light and shadow.

I. Complementary Material Properties: Unlocking New Possibilities for Curtain Wall Systems

UHPC (Ultra-High Performance Concrete), with its ultra-high strength, excellent durability, and design freedom, forms a striking contrast with the transparency and lightness of glass curtain walls. During the detailed design phase, Qinglong Group focuses on leveraging the compressive strength of UHPC (≥150MPa) and the light transmittance advantages of glass, achieving structural load reduction through modular design. For example, in a landmark project in Nanning, 30mm-thick UHPC decorative lines combined with ultra-clear glass not only met the structural requirements of a large-span cantilever, but also softened the cold feel of the glass curtain wall through the textured quality of UHPC, giving the building a visual effect that blends strength with softness.

II. Structural Collaborative Design: Solving Technical Challenges of Composite Curtain Walls

The differences in physical properties between the two materials demand precise structural calculations. Drawing on its experience participating in the development of the industry standard "General Technical Conditions for Non-Load-Bearing Ultra-High Performance Concrete (UHPC) Components," Qinglong's technical team established a collaborative load-bearing model for UHPC-glass curtain walls, focusing on three core issues: first, optimizing connection nodes through BIM technology, using stainless steel embedded parts and flexible seismic bearings to resolve thermal deformation stress; second, utilizing the fire resistance of UHPC (Class A1 non-combustible material) as fire isolation belts for glass curtain walls to enhance building safety ratings; third, achieving millimeter-level jointing precision between UHPC components and glass panels through parametric design, ensuring the overall flatness of the curtain wall.

III. Full Life-Cycle Management: Putting Qinglong's 28 Years of Experience into Practice

From detailed design to after-sales maintenance, Qinglong Group has built a quality control system covering the entire process. In manufacturing, automated production lines ensure dimensional deviations of UHPC components of ≤2mm; during construction and installation, 3D laser scanning technology achieves precise positioning; and in the after-sales phase, 10-year maintenance records are established. This integrated "design-production-construction-maintenance" service model shortened the construction period by 30% for a commercial complex project in Guangzhou, while extending the expected service life of the curtain wall system to over 50 years.

IV. Innovative Application Cases: Diverse Expressions of the Building Envelope

In the renovation project of Century Plaza on Nanjing East Road, the Qinglong team innovatively adopted a combination of light-transmitting UHPC and Low-E glass. Through the special texture design of the UHPC panels, sunlight passing through the glass creates dynamic light and shadow effects on the walls. The project won the "AALBORG WHITE Cup First UHPC Construction Engineering Innovation Award," confirming the unique advantages of combined curtain wall systems in enhancing the artistic value of buildings. In addition, in an airport terminal project in Malaysia, the combination of UHPC sunshades and glass curtain walls not only met the shading needs of the tropical region, but also achieved lightweight installation through GRP (glass fiber reinforced thermosetting plastic) connectors.

As a national high-tech enterprise and vice-chairman unit of the GRC Association, Qinglong Group has always upheld the mission of "creating beautiful architecture," promoting the standardized application of UHPC and glass curtain wall combined systems through material innovation and technology integration. In the future, as the concept of green building continues to deepen, this composite curtain wall solution that combines aesthetic expressiveness with structural safety will shine in more landmark projects, injecting new vitality into urban skylines.
