Can the Impact Resistance of UHPC Exterior Walls Withstand Typhoon Weather? Analysis of UHPC Wind Pressure Resistance Technology

UHPC exterior walls offer excellent impact resistance and can withstand Category 12 typhoons (wind pressure ≥1.1kPa). 15mm thick UHPC panels have a bending strength ≥18MPa and impact energy absorption ≥20J, which is 3-5 times that of ordinary concrete. Through reasonable design of connection nodes, the system's wind pressure resistance is ≥5.0kPa, meeting the requirements of coastal areas.

Wind tunnel tests show: under instantaneous wind pressure of ±6.0kPa, the maximum deflection of UHPC curtain wall panels is ≤L/200, with no loosening of connectors. A coastal super high-rise project withstood a typhoon with wind speeds reaching 45m/s, and the curtain wall remained intact. Qinglong UHPC optimizes design through finite element analysis to ensure wind resistance safety.
