Study Notes
Vertical-Plane Bracing
- Effective when symmetrically placed in building cores or perimeters to enhance stability.
- Can limit space-planning choices, particularly in tall structures where wind loading is a concern.
Strength and Rigidity
- Load application generates internal forces in structural elements and external forces at foundations.
- Structural elements must withstand peak loads without rupturing or excessive deflection.
- Adequate strength derived from appropriate cross-sectional sizing based on material strength.
- Structural calculations determine necessary sizes, informed by geometric rules or in-depth calculations.
Structural Calculations
- Consists of two phases:
- Structural analysis evaluates internal forces in building elements.
- Sizing calculations ensure elements can support these forces without failure.
Element Sizing Calculations
- Cross-sectional sizes must provide sufficient strength and rigidity to handle internal forces.
- Stress and strain concepts are utilized in the calculations for each individual element.
- Adjustments may be made through a cyclic design process to optimize element dimensions and overall structure form.
Timber as a Structural Material
- Features characteristics allowing lightweight and straightforward construction.
- Typically limited in scale due to its relative low strength and connection difficulties.
- Commonly used in domestic architecture for frameworks and horizontal load-bearing elements.
- Examples of applications include rafters, beams, trusses, and arches.
Composite Boards and Joints
- Composite boards like plywood and particle board provide enhanced dimensional stability and stress resistance.
- Finger joints allow for the connection of boards into longer elements, improving structural integrity.
- Composite materials are often used in secondary components and web elements of composite beams.
Structural Applications
- Timber's flexibility and tensile/compressive strength make it suitable for various loads, particularly in smaller buildings.
- Notable examples of large-scale timber structures include the Olympic Oval in Canada and the Savill Building in the UK.
Steel Structural Elements
- Steel shaping processes like hot-rolling and cold-forming result in varied cross-sectional shapes.
- Hot-rolling effectively reduces the cross-section of large steel billets into specific shapes for structural applications.
- Steel’s high strength allows for slender frameworks, enabling visually impactful designs with reduced structural volume.
