Study Notes
Introduction to Structural Systems
- Organized frameworks designed to bear loads while ensuring stability and safety of buildings.
- Manage forces from building weight, occupants, and environmental factors (e.g., wind, earthquakes).
Key Characteristics of Load-Bearing Structures
- Strength: Ability to withstand applied loads without breaking or deforming; includes dead loads, live loads, and environmental loads.
- Stability: Ensures structure remains in equilibrium and does not tilt, sway, or collapse under various forces.
- Cost-Effectiveness: Balances performance and safety against material and labor costs for overall durability.
Role of Structural Systems in Architecture
- Aesthetics: Influences a building's appearance and visual impact.
- Functionality: Enables functional, adaptable spaces; steel frames facilitate open floor plans.
- Durability: Well-designed systems enhance longevity against environmental challenges.
Role of Structural Systems in Safety
- Load Distribution: Distributes loads across the structure to prevent localized failures.
- Earthquake Resistance: Utilizes design features like base isolators to withstand seismic forces.
- Fire Resistance: Designed to slow fire spread, allowing more time for evacuation and minimizing damage.
Building Structure Components
- Superstructure: Elements above ground, including walls, columns, beams, floors/slabs, and roofs.
- Substructure: Elements below ground, comprising the basement and foundation.
Basic Components of a Structure
- Columns: Vertical elements carrying compressive loads from upper parts to the foundation.
- Beams/Girders: Horizontal elements supporting loads from slabs/roofs and transferring them to columns.
- Walls: Vertical structures that enclose space; can be load-bearing or non-load-bearing.
- Slabs: Flat surfaces like floors/roofs that distribute loads.
- Truss: Frameworks of triangular units providing additional support, commonly used in roofs.
Design Considerations
- Site Conditions: Analyze soil characteristics, topography, and environmental impact.
- Site Constraints: Includes zoning laws, building codes, and natural hazards affecting development.
Load Considerations
- Dead Loads: Permanent, static loads from the structure itself.
- Live Loads: Dynamic loads that can change, like people and furniture.
- Environmental Loads: Includes wind pressure, snow, and seismic forces with specific design codes.
Material Selection Criteria
- Common Materials: Concrete, steel, timber, and masonry.
- Criteria: Based on strength, durability, cost, and environmental impact.
Serviceability Criteria
- Ensures the structure remains functional and comfortable during use; distinct from safety considerations.
Cost Estimation and Budgeting
- Essential for project planning, ensuring financial feasibility while meeting structural performance requirements.
