Can Aluminum Curtain Walls Withstand Strong Wind Loads and Seismic Movements in Skyscrapers?

Yes — aluminum curtain walls can be designed to withstand the demanding wind and seismic conditions typical of skyscrapers, provided they’re engineered with correct performance criteria. For wind, performance is driven by local design pressures, building height and terrain exposure. Engineers use wind tunnel data or code-based calculations to size mullions, determine deflection limits and select glazing thickness. In the Gulf region (e.g., Dubai, Doha) where wind-driven sand and high gusts are concerns, curtain walls incorporate larger drainage cavities, durable gaskets, and robust anchorage to resist both static and dynamic loads. Seismic performance depends on detailing: curtain walls are non-structural but must accommodate differential movement between floors and the structural frame. This is achieved through flexible anchors, sliding connections and movement joints that permit in-plane and out-of-plane displacement without damaging glazing or sealants. Projects in Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan) with notable seismicity should use performance-based seismic articulation for façade attachments and specify tested systems with cyclic movement capacity. System testing to standards such as ASTM, EN or local equivalents, plus mock-up testing under combined loads, verifies that the curtain wall will meet serviceability and safety requirements. Coordination during design between structural and façade engineers ensures anchor locations, load paths and tolerances are compatible, delivering façades that resist wind and seismic demands while maintaining weather tightness and occupant safety.
