Shaft Wall Assembly at Bottom of Shaft with Beam Support
Required to provide a rated base to the shaft without using the 3-ply CLT floor to support it; glulam beams support the concrete-filled metal deck.
Shaft Wall Assembly at Bottom of Shaft with Beam Support
Description: Required to provide a rated base to the shaft without using the 3-ply CLT floor to support it; glulam beams support the concrete-filled metal deck.
Purpose: Maintain rating of base of shaft wall assembly.
Design Notes
- Glulam beam used to support the shaft wall and the concrete-filled metal deck shaft floor based on char factor compliance for wall rating.
- CLT floor outboard of shaft wall assembly to maintain shaft wall rating without CLT support.
Acoustics:
- Shaft wall assembly estimated at STC 39-45 depending on layers of gypsum for shaft rating CLT floor 3-ply (3.5″) with 3/4″ acoustic mat and 3″ concrete = IIC 45 & STC 53.
Fire:
- Can be used to meet any shaft wall rating requirement based on size of glulam and associated char factor.
- Const.
- Constructability Moderate
- Fire
- Fire Rated Up To 2 Hours
