Truss Types by Shapes

Pratt Truss

Design:

  • The diagonals are sloped toward the centre in tension under normal loads.
  • Vertical members are in compression.
  • Characterized by a simple and repetitive structure with many triangular shapes.

Application:

  • Commonly used in bridges and large-span industrial structures.

Advantages:

  • Efficient in handling heavy loads with less material.
  • Easy to fabricate and assemble.
  • Best suited for spans with uniformly distributed loads.

Warren Truss

Design:

  • Consists of equilateral or isosceles triangles with no vertical members.
  • Both compression and tension forces are spread throughout the structure.

Application:

  • Widely used in railway bridges, roof structures, and temporary scaffolding.

Advantages:

  • Simple geometry and fewer members reduce fabrication costs.
  • Good load distribution; ideal for evenly distributed loads.
  • Lighter than other trusses for the same span.

North Light Truss

Design:

  • Features a sloped roof on one side and a near-vertical face on the other, often paired with glazing for natural light.
  • Typically a combination of trusses, beams, and purlins.

Application:

  • Frequently used in industrial buildings, factories, and workshops where natural lighting is essential.

Advantages:

  • Provides excellent daylighting, reducing electricity usage.
  • Ideal for large areas requiring ventilation and light.
  • Allows integration of roof-mounted systems like HVAC or solar panels.

Saw-tooth Truss

Design:

  • Similar to the North Light truss but features repetitive, triangular ridges with one side steeper than the other.
  • Often includes glass or transparent sections for light.

Application:

  • Used in factories, industrial sheds, and greenhouses.

Advantages:

  • Maximizes natural light and ventilation.
  • Effective for energy-efficient designs.
  • Ideal for locations with high ceilings or large spans.
Truss Type Load Handling Material Usage Best Use Complexity
Pratt Truss Heavy Loads Moderate Bridges, industrial Moderate
Warren Truss Distributed loads Minimal Bridges, scaffolding Simple
North Light Truss Large spans, natural light Heavy Factories, workshops Complex
Saw Tooth Truss Large spans, natural light Heavy Factories, sheds Moderate
Steel Pipe Truss

Truss Types by Geometry

Box Truss

Box trusses consist of four interconnected trusses forming a box or rectangular shape in cross-section. The closed geometry provides high rigidity and torsional resistance.

Features:

  • Formed by combining two or more planar trusses to create a 3D structure.
  • Excellent at resisting bending, twisting, and shearing forces.

Uses:

  • Bridges: Widely used for long-span bridges due to torsional strength.
  • High-rise building frames: Provides stability against lateral loads like wind or seismic forces.

Examples:

  • Warren Box Truss: A combination of triangular forms in a box-like configuration.
  • Double Warren Truss: Multiple Warren trusses connected to form a box.

Ladder Truss

Ladder trusses consist of parallel upper and lower chords connected by vertical or diagonal members, resembling the structure of a ladder.

 

Features:

  • Simpler design compared to triangular or box trusses.
  • Efficient for carrying loads primarily in one direction.

Uses:

  • Floor supports: Often used in open-web steel joists for floors or ceilings.
  • Secondary roof framing: Common in lightweight structures where bending resistance is prioritized.

Example:

  • Parallel Chord Trusses: A type of ladder truss with straight top and bottom chords and webbing between.

Triangle Truss

These trusses use triangular geometry as the core structural form which makes them significantly more efficient for distributing loads.

Features:

  • Triangular trusses are inherently stable due to their geometric shape, which efficiently distributes loads and resists deformation.

Uses:

  • Common in roof structures, bridges, and small-span applications where stability and strength are critical.

Examples:

  • Pratt Truss: A triangular design where diagonal members slope towards the center.
  • Fink Truss: Multiple triangular patterns ideal for steep roof slopes.
  • King Post Truss: A single triangular truss with a central post, often used for short spans
Truss Geometry Advantages Disadvantages Applications
Triangular High strength-to-weight ratio; ideal for roofs. Limited torsional resistance. Roofs, bridges, small-span structures.
Box Excellent rigidity and torsional strength. More material and complexity in fabrication. Long-span bridges, towers, high-rise buildings.
Ladder Simple and lightweight; easy to fabricate. Less efficient for long spans or heavy loads. Floors, ceilings, lightweight roof frames .
Truss Type Footbridge

Pros and Cons of Steel Trusses

Pros

  • Ideal Load Distribution:The flexible geometry allows designers to provide ideal load distribution along the truss.
  • Long Span Coverage: Trusses are ideal solution for long span applications and offer better weight ratio compared to traditional beams.

  • Strong load-bearing capacity: Trusses offer higher load bearing capacity with a better strength-to-weight ratio which makes them ideal solution for long span applications

  • Effective use of materials: Trusses offer lighter structures which allows an easier, faster and more securely fabrication and installation.

Cons

  • Complex Design and Fabrication: Trusses are harder to design and build because they have many members and joints. Beams are simpler.
  • Not Ideal for Short Spans: Trusses are better for long spans, but for short spans, beams are cheaper and simpler.
  • Transportation Challenges: Large trusses occupy more space and length which makes transport challenging and often costly

Steel Truss vs Steel Beam

Steel trusses excel in handling large spans and distributed loads, but steel beams offer simplicity, faster installation, and cost-effectiveness for short spans or simpler applications. The choice depends on the specific needs of the project.

Steel Truss Steel Beam
Design Complexity High, due to multiple members and joints Simple linear design
Installation Time Longer due to assembly Quicker to install
Connections Heavier and more material-intensive Lighter and simpler
Aesthetics Industrial, cluttered appearance Clean and streamlined
Maintenance More joints require frequent inspection Less maintenance required
Suitability for Spans Best for long spans Ideal for short spans
Load Type Better for distributed loads Better for point loads
Transport Challenging for large trusses Easier to transport
Cost Higher for smaller projects More economical for small projects

How to select the right Truss ?

  • Load Requirements:
    Understand the specific loads (dead, live, wind, and snow) your truss system must bear. Collaborate with structural engineers to determine the appropriate design and material grade
  • Span Length: Longer spans require careful design to prevent deflection or failure. Steel trusses are well-suited for long spans but may require additional bracing or supports for extreme lengths.

  • Material Specifications: Ensure the steel meets necessary standards (e.g., ASTM or ISO). Factors like tensile strength, yield strength, and corrosion resistance are critical.

  • Fabrication and Coating:

    • Galvanization or Powder Coating: Protects against rust in corrosive environments.
    • Welding Standards: High-quality welding ensures structural integrity.
  • Cost and Availability

    • Compare suppliers for pricing, lead times, and transportation options.
    • Pre-fabrication can reduce costs but may limit on-site adjustments.
  • Environmental Conditions: Corrosive environments (e.g., coastal or industrial areas) may require specialized steel grades or coatings for longevity
