3-D Animation of Test Specimen
Sprinkler Piping Subsystems Test Specimen on NCS
UB-Nonstructural Component Simulator
Two-level shake table capable of reproducing in real-time the full-scale floor motions expected at two consecutive building levels
Partitions Subsystem In-Plane Experiments
Specimens 1, 2 & 3 (Basic), & Specimen 4 (Gypsum connected to top track)
• Top “slip track” acted as intended:
- Limited damage observed in in-plane wall
- Damage concentrated in return walls top tracks
- Spec 4 performed similarly to specs 1 to 3 after failure of connection of gypsum to top track
- Crushing of gypsum in wall corners
Partitions Subsystem In-Plane Experiments
Specimens 11, 12 & 13 (Bookshelves attached)
• Damage concentrated along cornerbeads
• No damage observed around attachments of bookshelves to partition walls
• Books in bookshelf fell down
Partitions Subsystem In-Plane Experiments
Specimens 14, 15 & 16 (Simulated rigid ceiling)
• Equivalent rigid ceiling weight attached to the walls
• Damage similar to specimens w/bookshelves attached
Partitions Subsystem Out-of-Plane Experiments
Specimens 40, 41 & 43, and 39, 45 & 47
(Bookshelf/Walls without and with Returns)
• Screws pulled out from gypsum to stud connections & damage in bookshelf connectors
• Damage along horizontal joints between gypsum wallboards and along cornerbeads
• Collapse of Specimens 40, 43b & 47 (All of them, re-used walls)
Partitions Subsystem Out-of-Plane Experiments
Specimens 42, 44 & 46 (eq. ceiling/Walls w/ returns)
• Gypsum boards crushed around fence staples connection
• Screws pulled out from gypsum to stud connections
• Damage at top and bottom ends of cornerbeads
• Equivalent ceiling completely detached from wall
(Specimen 46)
Partition Wall Subsystems Out-of-Plane Experiments
Specimens 48, 49 & 50 (Partial Height Braced Walls with Returns)
• Screws pulled from connection of braces to top track
• Buckling of steel braces
• Buckling of top track around brace connections
Partition Wall Subsystems Out-of-Plane Experiments
Specimens 48, 49 & 50 (Partial Height Braced Walls with Returns)
• Screws pulled from connection of braces to top track
• Buckling of steel braces
• Buckling of top track around brace connections
