Analysis of Key Technologies and Design Considerations for Combined Application of UHPC Curtain Walls with Glass Curtain Walls

As the "outer garment" of modern architecture, building curtain walls are not only a carrier of aesthetic expression but also a stage for technological innovation. When UHPC curtain walls, combining ultra-high strength with artistic plasticity, meet the transparent and lightweight glass curtain wall, how can we achieve an architectural effect of 1+1>2? As an industry player with 28 years of deep expertise in the UHPC/GRC/GRG/GRP materials field, Qinglong Group will analyze the key technologies and design logic of this combined application from three dimensions: material properties, structural coordination, and process integration.

1. Performance Synergy of UHPC and Glass Curtain Walls: The Underlying Logic of Complementary Advantages

UHPC (Ultra-High Performance Concrete), with its compressive strength exceeding 200MPa, excellent durability, and freedom of form, has become an emerging force in the curtain wall field; glass curtain walls, meanwhile, dominate the mainstream market with their advantages of light transmission, modernity, and lightweight design. The core of their combined application lies in performance complementarity: UHPC can undertake structural support and personalized decorative functions, while glass is responsible for daylighting and extending views. For example, in commercial complex projects, UHPC is used to create faceted sun-shading canopies paired with full-glass curtain wall systems, which not only meets energy-saving requirements but also creates a strong visual impact through material contrast. In a landmark project in Nanning, Qinglong Group achieved a technical breakthrough by combining UHPC components with Low-E glass, reducing the heat transfer coefficient of the curtain wall system by 15%.

2. Key Control Points in Structural Design: From Load Transfer to Joint Treatment

The safety of combined curtain walls depends on refined structural design. First, the load coordination between UHPC components and the glass curtain wall must be addressed: although the self-weight of UHPC is only 1/3 that of traditional stone, the supporting structure still needs to be optimized through finite element analysis to avoid stress concentration caused by stiffness differences. Second, joint treatment must take into account both waterproofing and seismic performance. Using a "flexible connection + sealant caulking" process, Qinglong's technical team successfully resolved the challenge of coordinating expansion and contraction deformation between UHPC decorative lines and the glass curtain wall in a cultural center project in Guangzhou. In addition, special attention should be paid to controlling the spacing between glass edges and UHPC components; a temperature joint of 8-12mm is generally recommended to ensure free deformation of the materials.

3. Process Integration and Full-Chain Control: From Detailed Design to Construction

As a UHPC/GRC manufacturer integrating detailed design, production, and installation, Qinglong Group emphasizes full-process coordination for combined curtain walls. In the design phase, BIM technology is used for parametric modeling to simulate in advance the assembly precision of UHPC components and glass panels; in production, automated production lines ensure that the dimensional deviation of UHPC components is ≤2mm, while a synchronized production scheduling mechanism is established with glass processing manufacturers; in the construction phase, 3D laser scanning technology achieves millimeter-level installation positioning. Taking a commercial landmark in Shenzhen as an example, the combined application of its double-curved UHPC curtain wall and point-supported glass curtain wall, through Qinglong's full-chain control of "design-production-installation," shortened the on-site construction period by 20%.

4. Sustainability and Cost Optimization: Considering Long-Term Value

The design of combined curtain walls must balance initial cost with full life-cycle value. The high durability of UHPC materials reduces later maintenance costs, with a service life of over 100 years far exceeding that of traditional curtain wall materials; glass curtain walls can improve building energy efficiency by selecting energy-saving products such as photovoltaic glass. In a green building project in Foshan, Qinglong Group adopted a combination of UHPC and photovoltaic glass, achieving a comprehensive building energy-saving rate of 75% and shortening the investment payback period to 8 years. In addition, standardized module design and the development of universal joints can effectively reduce the customization costs of UHPC components, further highlighting the economic advantages of combined curtain walls.

The combined application of UHPC and glass curtain walls represents a deep integration of materials science and architectural aesthetics. As a national high-tech enterprise and a participant in industry standard-setting, Qinglong Group has always taken "creating beautiful architecture" as its mission, providing designers and owners with integrated solutions from concept to implementation through 28 years of technical accumulation and full-chain service capabilities. In the future, with the continuous improvement of UHPC material performance and the development of digital construction technology, this combination will shine in more landmark buildings, redefining the technical boundaries and artistic expression of modern curtain walls.
