Study Notes
Fire Types
- Type I: Fire resistive construction provides the highest level of fire safety.
- Type II: Non-combustible or protected noncombustible materials used.
- Type III: Exterior protected construction, often involving masonry elements.
- Type IV: Utilizes heavy timber materials for structural integrity.
- Type V: Wood frame construction allows all major structural components to be combustible.
Legal Requirements
- Building designs must comply with building codes and accessibility requirements.
- Structures are initially classified based on materials used in construction.
Fire Resistance
- Type I construction has the highest fire resistance requirements.
- Type II construction permits structural components with lower fire resistance than Type I.
Occupancy and Fire Load
- Occupancy classification groups buildings by similar fire risks.
- Total combustible materials in a space is referred to as fuel load.
- Fire load is defined as the weight of combustible material per square foot.
Structural Considerations
- Structural designs calculate loads to ensure buildings withstand common forces.
- Stress indicates how forces impact structural members.
- Force of gravity is the most common load acting on a structure.
- Shear stress involves sliding planes of material past each other.
Load Types
- Dead load refers to fixed, quantifiable loads.
- Live load includes variable loads like snow and rain.
- Firefighting operations can add additional live loads to structures.
Wind and Seismic Forces
- Wind forces are primarily considered in terms of direct pressure.
- Seismic forces arise from tectonic plate movement along fault lines.
Structural Members
- Soils exert lateral loads against foundations.
- Beams must resist deformation from applied loads.
- Columns are designed to support axial loads.
- Arch structures primarily deal with compressive loads.
Structural Units
- Cables are typically made of steel strands.
- Trusses are frame units made up of triangles, providing structural stability.
- Space frames are three-dimensional truss structures enhancing load distribution.
Load-Bearing Structures
- Load-bearing walls carry compressive loads and offer lateral support.
- Frame structures utilize supports akin to the human skeleton.
Fire Risks in Design
- Vertical shafts and utility chases can become fire origin points and pathways for fire and smoke.
- Refuse chutes must be constructed of noncombustible materials with rated doors and fire-rated enclosures due to combustible waste buildup.
- Grease ducts transport grease vapors vertically using in-line or rooftop fans.
HVAC Systems
- Heating, ventilating, and air conditioning (HVAC) systems focus on creating and maintaining occupant comfort within buildings.
