picking up from last week…

•Fire stair layout•Due October 18th

Assignment #1

Requirements

Use your studio project building dimensions Floor to floor heights Thickness of exterior walls and interior

partitions (they’re different) Use your design to calculate the

occupant load

Step 1: calculate occupant load

Step 2:Calculate dimension of egress components

•Plans, sections (2), and hidden elevation of center guard rail/hand rail•To scale•Fully dimensioned•Printed in black and white on 24x36” paper

Step 3: Design fire stair

other things to include

General project data: Use Group, Construction Type, codes in effect

Rize/run calculation Enlarged detail of the stair nosing Drawing indicating handrail mounting

and clearance

Fire Resistant Materials and Assemblies

Fire / Smoke Protection Systems

Passive systems: prevent fires Fire and smoke barriers Finishes and furniture

Active systems: once a fire has started Detection Extinguishing / Suppression Emergency lighting

Exiting systems: architectural elements Means of egress

“Compartmentation”

Passive fire protection means

The separation of areas in a building to control fire and smoke

Use Wall, Floor, and Ceiling Assemblies

“Fire resistance” (of assemblies) vs. “fire protection” (of penetrations in those assemblies)

“Fire barriers” (for compartmentation) vs. “fire and smoke partitions” (not specific to egress; residential, tenant spaces)

•All use standard materials•Sometimes in standard configurations
