Abstract of: Glass Facades Under Seismic Events and Explosions: a Novel Distributed-TMD Design Concept for Building Protection

Glazing facades generally represent one of the most critical building components, from a structural point of view, since providing a physical separation and barrier for the building occupants. In this regard, especially under the action of extreme loads, they require specific design concepts voted...
