Key Design Points for UHPC Curtain Wall Wind Load Resistance: Qinglong Landmark Project Practice

Wind load resistance is a core indicator for the safe application of UHPC curtain walls in buildings, especially in high-rise buildings, coastal areas, or strong wind regions, where design rationality directly affects building safety. Qinglong Group, an enterprise that has undertaken numerous landmark projects, combines 28 years of engineering experience to analyze the core points of wind load resistance design for UHPC curtain walls.

I. Core Basis and Calculation Standards for Wind Load Resistance Design UHPC curtain wall wind load resistance design must follow the "Load Code for the Design of Building Structures" and the "General Technical Conditions for Ultra-High Performance Concrete (UHPC) Non-Load-Bearing Components". The core basis includes the basic wind pressure of the project area, building height, shape coefficient, and ground roughness. Calculations must take into account the standard value of wind load and wind suction effects; for example, when the basic wind pressure in coastal areas is ≥0.7kN/㎡, the design must be reinforced with a 1.3 coefficient. In the Hainan International Convention and Exhibition Center project, Qinglong adopted wind tunnel tests to simulate actual forces under the coastal strong wind environment, ensuring design precision.

II. Key Measures to Improve the Wind Load Resistance of UHPC Curtain Walls Improving wind load resistance requires starting from three dimensions: material, structure, and connection. In terms of material, UHPC itself features high strength (compressive strength ≥120MPa), and Qinglong further enhances the material's crack resistance and impact resistance by optimizing fiber content and aggregate ratio. In terms of structure, panel thickness (conventionally 20-50mm, can be increased to 60mm for high-rise buildings) and keel spacing are rationally designed to reduce deformation under wind loads. In terms of connection, a hanging system featuring "multi-point fixation + elastic connection" is adopted; in the Shenzhen Pingshan High-tech Zone Comprehensive Service Center project, the combination of stainless steel high-strength hangers and elastic gaskets improved wind load resistance stability.

III. Qinglong's Landmark Project Practices in Wind Load Resistance Design As a national "Specialized, Refined, Distinctive, and Innovative" enterprise, Qinglong has accumulated rich experience in multiple high-difficulty wind load resistance projects. In the Shanghai Astronomy Museum public art project, for UHPC sculpture components at heights above 3 meters, a composite structural design of "main load-bearing + lateral wind resistance" was adopted to successfully withstand strong coastal winds. In the Guangxi New Media Center project, facing the complex stress conditions of the hyperbolic UHPC curtain wall, BIM technology was used to simulate wind load distribution and optimize the hanger layout, ensuring a wind load resistance capacity of over 2.5kN per square meter. In addition, Qinglong has established a wind load resistance performance testing system, and all products pass simulated wind load tests before leaving the factory.

UHPC curtain wall wind load resistance design requires comprehensive consideration of the regional environment, building height, and structural form, and cannot be generalized. With 28 years of engineering experience and technical R&D strength, Qinglong Group provides customized wind load resistance solutions for different scenarios, having completed hundreds of projects in high wind load areas without any safety accidents. Choosing a supplier with engineering experience and technical strength is the key to ensuring that UHPC curtain wall wind load resistance performance meets standards.
