Can UHPC Exterior Walls' Impact Resistance Withstand Typhoon Weather? — Safety Performance Verification and Design Standards

The impact resistance of UHPC exterior walls is key to withstanding extreme weather such as typhoons. Based on wind tunnel tests and project practice, Qinglong Group holds that high-quality UHPC panels should have an impact resistance energy of ≥10J and a wind pressure resistance of ≥3.0kPa. Through material reinforcement and connection optimization, they can effectively meet the challenges of typhoons and ensure building safety.

The material itself offers strong impact resistance. UHPC has a flexural strength of ≥15MPa and good toughness, absorbing energy through micro-cracks upon impact. In coastal projects, Qinglong Group added steel fibers (2%-3% by volume), raising the impact resistance energy to over 15J. The connection system is secure, with hangers providing a pull-out resistance of ≥10kN to prevent panels from detaching. Through these measures, UHPC exterior walls perform reliably in typhoons.
