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.
