Analysis of Key Technical Points and Design Strategies for Combined Application of UHPC Curtain Walls and Glass Curtain Walls

At the intersection of contemporary architectural aesthetics and technological innovation, the combined application of UHPC curtain walls and glass curtain walls is becoming a key choice for shaping urban skylines. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group, with its integrated capabilities in detailed design, manufacturing, construction and installation, and after-sales maintenance, deeply understands the technical code behind the synergistic application of these two materials. This article analyzes the core technical points of combined curtain wall systems from three major dimensions—complementary material properties, structural safety design, and performance optimization strategies—providing designers and owners with solutions that combine aesthetic value with engineering feasibility.

**Synergistic Properties of UHPC and Glass Curtain Walls: From Functional Complementarity to Aesthetic Resonance**

Ultra-high performance concrete (UHPC), with its ultra-high strength (compressive strength up to 150-200MPa), excellent durability, and freedom of form, naturally complements the transparency of glass curtain walls. In a commercial complex project in Shenzhen, the Qinglong team combined precast UHPC sunshades with Low-E glass, achieving a 30% improvement in shading efficiency through parametric design, while leveraging UHPC's sculptural surface texture to give the building a three-dimensional character under nighttime lighting. This "hardness and softness in balance" material combination not only meets the structural load-bearing requirements of large-span curtain walls, but also dissolves the heaviness of UHPC through the lightness of glass, confirming the core value of new decorative building materials in facade innovation.

**Building a Structural Safety System: From Joint Design to Load Transfer**

The safety core of combined curtain walls lies in solving the connection and coordination between the two materials. In a cultural center project in Guangzhou, the Qinglong technical team innovatively developed a "UHPC rib panel-glass unit" composite support system: pre-embedded stainless steel connectors achieve rigid connections between UHPC components and the main structure, while elastic rubber pads buffer the thermal deformation of glass panels. Third-party testing showed that this solution's wind pressure resistance meets level-12 typhoon standards, with a seismic fortification intensity of 8 degrees. Notably, the lightweight nature of UHPC components (density only 1.8 times that of traditional concrete) significantly reduces the overall curtain wall load, making large cantilevered forms feasible—this is precisely the technical advantage Qinglong demonstrates as a custom UHPC product manufacturer in the detailed design phase.

**Full-Process Performance Optimization: From Material Selection to Intelligent Construction**

Maximizing the performance of combined curtain walls requires full-chain technical control. At the material level, Qinglong uses its self-developed UHPC formula (fiber content 2.5%), reducing component thickness by 40% compared to traditional GRC, while improving impermeability through nano-silane treatment. The production process employs BIM + robotic carving technology, ensuring the geometric precision of UHPC components is controlled within ±1mm, laying the foundation for precise glass curtain wall installation. The construction phase innovatively adopts a "unit-based modular" installation process, reducing on-site work time by 30%—a technical approach successfully validated in projects such as the Nanning ASEAN Culture and Art Center. As a national high-tech enterprise, Qinglong has always driven product upgrades through technological innovation, participating in the formulation of industry standards such as the "General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)", providing regulatory guidance for combined curtain wall applications.

The combined application of UHPC and glass curtain walls represents a perfect fusion of materials science and architectural art. With 28 years of professional accumulation, Qinglong Group, guided by its mission of "creating beautiful architecture", will continue to explore innovative applications of new decorative materials in building facades. Whether it is the formal breakthroughs of landmark buildings or the performance optimization of commercial complexes, choosing solutions that combine design freedom with engineering reliability is the key to balancing architectural aesthetics with technical value. Let us join hands to create architectural works with both visual impact and lasting vitality, injecting new energy into urban spaces.
