How far from the the building should the collapse zone be for apparatus?
|
1.5 times the height, place apparatus on the corners if possible.
|
|
|
What are the 3 principle members of a truss?
|
- top cord
- bottom cord - web members |
|
|
What are 4 types of wood construction?
|
- Wood
- Balloon - Timber - Log Frame |
|
|
What are the 5 types of Consruction?
|
Type 1: Fire Restistive (high rise)- structural members are non-combustible and have a specified fire restistance
Type 2: Non-Combustible (Steel truss)- structural members are non-combustible and may be protected, but requirments of fire restistance are limited or nonexistent. Type 3.Ordinary (Masonary walls)- Exterior walls are normally non-combustible. Internal structural members and assemblies are contsructed of strictly combustible material, or a mixture of combustible and non-combustible material. Type 4.Heavy Timber (Old big beams)- Exterior walls are normally non-combustible and internal structural members are composed of heavy wooden timbers. Type 5. Wood Frame (houses)- The majority of structural components are constructed of combustible material. Limited fire resistence can be specified for larger structures. |

What is the difference between Platform Framing vs. Balloon Framing?
|
Platform requires the floor of a particular storey to be completed and sheeted, followed by the construction of the exterior and interior load-bearing walls. The joists for the next floor are installed on top of the walls and sheeted. The top plate of the studded wall acts as a fire stop.
Balloon Frame - is composed of long studs in the walls that run the full height of the structure, floor joists are hung from the studs thereby creating voids that allow fire to extend up inside walls to upper floors and attic space |
