Abstract

"Provisions for the structural design of architectural glass under seismic loadings are non-existent in current model building codes in the United States. To begin addressing this serious void in the structural design of curtain wall systems, a pilot study was conducted at the University of Missouri- Rolla to evaluate the performances of various architectural glass types subjected to dynamic motions. A test facility was constructed to accommodate in-plane, in-plane/out-of-plane, and in-plane/torsional motions. A wide mullion, dry-glazed curtain wall system with generous glass-to-aluminum clearance was used for all tests. All glass types tested were subjected to the same test spectrum.

Glass fallout under different dynamic motions ranged from zero fallout to as high as 87% fallout. Annealed and heat- strengthened laminated glass units resisted glass fallout completely, while fully tempered laminated glass units did not. Thicker annealed monolithic and heat-strengthened monolithic glass lites resisted glass fallout well, but thinner annealed monolithic glass lites (with or without unanchored PET film) were highly prone to glass fallout. Adding out-of-plane motions to in-plane motions increased the observed glass fallout rates to a small-to-moderate extent. However, in-plane/torsional motions did not induce fallout in glass types that showed complete resistance to fallout under in-plane and in-plane/out-of-plane motions"--Abstract, page iii.
