Study Notes

Mixed Construction

Mixed construction occurs when a new structure is built atop an existing one of a different construction type, often seen in older remodeling projects.

Fire Barriers

Fire barriers are crucial as they must maintain their integrity; continuity destruction renders them ineffective.

Building Classifications

Building classifications in codes are primarily based on fire resistance ratings of structural components rather than materials or costs.

Fire Resistance Tests

The standard fire-resistance test establishes required performance standards in building codes, essential for safe construction practices.

Structural Framing and Fire Types

Building types with significant fuel contributions to fires include Types III, IV, and V due to their construction materials.

Structural Assembly Integrity

Fire resistance measures a structural assembly's capability to maintain load-bearing capacity under fire conditions.

Standardized Testing

The universally accepted test for fire resistance under building codes is the ASTM E-119 test.

Type II-A Construction

Type II-A construction mandates that structural components have at least a one-hour fire resistance rating.

Height and Area Limitations

Building construction and occupancy classifications set restrictions on permissible building heights and designated open areas to ensure safety.

Type V Construction Restrictions

Type V buildings face maximum height and area restrictions due to their potential exposure threat to nearby structures during serious fires.

Type IV Construction Characteristics

Type IV construction uses wood components that possess greater mass in comparison to Type III structures, enhancing fire resistance.

Fire Resistance Calculation Methods

Calculating fire resistance involves long-term data from laboratory testing of materials rather than singular tests or anecdotal evidence.

Fire Load Definition

Fire load refers to the maximum heat that can be released if all fuel within a structure is consumed.

Concerns with Type III Construction

A primary concern with Type III construction includes the risk posed by combustible concealed spaces within the structure.

Noncombustible Construction Type

Type IV construction is categorized as noncombustible or protected noncombustible, indicating high fire resistance.
