Study Notes
Wind-Borne Debris Region
- Designates areas in hurricane-prone regions that are exposed to debris propelled by strong winds.
Substantial Structural Damage
-
Definition: Structural damage classification when:
- Vertical elements in the lateral force-resisting system experience over 33% reduction in lateral load capacity.
- Any vertical component supporting over 30% of the structure's floor and roof area sees over 20% reduction in capacity, with remaining capacity less than 75% of the required value for new buildings.
Floor Live Load
- Refers to the loads from occupants and furniture; must be indicated for design and may involve reduction methods.
Earthquake Design Data
- Must include vital seismic information in designs, such as risk category, seismic importance factor, mapped spectral acceleration, and design base shear.
Special Loads
- Buildings must indicate special loads relevant to the structure’s design, including photovoltaic systems which must have their dead load specified.
Structural Deflection Standards
- Reinforced concrete, steel, masonry, and aluminum structural members must adhere to specific deflection limits as per relevant codes (e.g., ACI 318, AISC 360).
Structural Walls
- Must provide load-bearing resistance and be anchored properly to ensure stability against lateral forces.
Diaphragm Stiffness
- A diaphragm is considered rigid for shear distribution when its lateral deformation is within twice the average story drift limits.
Risk Category Assignment
- Each building must be assigned a risk category based on occupancy and related standards, ensuring appropriate safety measures are in place.
Structural Actions Resistance
- Members and systems must be designed to resist forces from earthquakes and wind, with load paths that transmit forces to the foundation.
Uniform Live Loads
- Live loads should reflect maximum expected use but must comply with minimums specified in design codes, ensuring safety and stability.
Concentrated Live Loads
- Surfaces must sustain either prescribed uniformly distributed or concentrated loads, whichever demands greater structural performance.
Partition Loads
- Weight considerations for partitions are required unless minimum specified live load thresholds are met.
Attic Live Load Specifications
- Attic live load applies to specific accessible sections; non-accessible portions have distinct load requirements.
Handrails and Guards
- Must withstand specified loads including a linear load of 50 plf and concentrated loads of 200 pounds.
Vehicle Barriers
- Designed to resist concentrated loads of 6,000 pounds for passenger vehicles.
Elevator Load Design
- Components exposed to dynamic elevator loads need to accommodate specified impact loads and deflection limits.
Machinery Load Considerations
- Machinery weight considerations must include an increased load for impact depending on the type of machinery.
Passenger Vehicle Garages
- Live loads in these structures cannot be reduced, ensuring adequate support is always maintained.
Live Load Reduction Provisions
- Certain structural elements can have live loads reduced under strict conditions, with exceptions recognized for design flexibility.
Occupiable Roof Specifications
- Roofs designated for occupancy may have reduced live loads, with specific guidelines for landscaped areas defined by soils’ saturation considerations.
