A Review of Seismic Performance for Building Curtain Walls in High-Ductility and High-Toughness Steel Structures

The relatively low self-weight of building curtain walls leads to reduced seismic forces， which often causes their seismic performance to be overlooked. Research on key technologies for damage control and toughness enhancement in high-ductility steel structures has significantly improved the resilience of steel structures after strong earthquakes. This improvement has subsequently strengthened the foundational seismic safety of steel-structure building curtain walls， thereby raising new requirements for their post-earthquake survival probability and serviceability. Based on the current state of seismic research on brittle panel curtain walls such as stone curtain walls and glass curtain walls， this paper elaborates the key techniques for damage control and toughness enhancement in high-ductility steel structures. It analyzes the significant advantages of high-ductility and high-toughness steel structures in enhancing the seismic performance of brittle panel curtain walls.
