Here's a concise comparison of steel truss bridge types and their key differences:

Types of Steel Truss Bridges

TypeConfigurationSpan RangeKey FeaturesProsConsBest For
Warren TrussEquilateral triangles50-250mUniform load distributionLightweight, fewer membersRequires precise connectionsHighway/railway bridges
Pratt TrussDiagonal slopes to center (↓)50-150mEfficient for point loadsSimple design, good for heavy loadsMore material than WarrenRailway bridges
Howe TrussDiagonal slopes from center (↑)30-100mBetter for timber combosEasy assemblyLess efficient than PrattHistoric/rehab bridges
K-Truss"K" shaped web members100-350mHigh stabilityResists bucklingComplex fabricationLong-span heavy loads
Baltimore TrussPratt variant with sub-beams100-200mExtra stiffnessHandles heavy point loadsHigher costHeavy rail bridges
Parker TrussCurved top chord80-300mArch-like shapeAesthetic appealComplex engineeringLandmark bridges
Lenticular TrussLens-shaped (top/bottom curves)50-150mAerodynamicWind-resistantLimited span capacityScenic/pedestrian bridges
Bailey TrussModular panels30-60mPrefabricatedRapid deploymentLower load capacityMilitary/temporary bridges

Key Differences Explained

  1. Load Transfer:

    • Pratt/Howe: Ideal for concentrated loads (railway traffic)

    • Warren: Best for uniform loads (highway bridges)

    • K-Truss: Handles combined loads (heavy + dynamic)

  2. Span Efficiency:

    • Short spans (<100m): Pratt/Howe

    • Medium spans (100-200m): Warren/Baltimore

    • Long spans (>200m): K-Truss/Parker

  3. Construction Complexity:

    • Simple: Warren (fewer members)

    • Complex: K-Truss (many small elements)

    • Rapid: Bailey (modular assembly)

  4. Aesthetics:

    • Industrial: Pratt/Warren

    • Architectural: Parker/Lenticular

  5. Material Usage:

    • Most efficient: Warren (least steel)

    • Least efficient: Howe (more members)

Selection Guide

  • Railway Crossing: Pratt/Baltimore (handles heavy point loads)

  • Highway Bridge: Warren (cost-effective for medium spans)

  • Emergency Use: Bailey (quick assembly)

  • Signature Design: Parker/Lenticular (visual impact)

  • Extreme Span: K-Truss (stability for >300m)

Technical Notes

  • Warren trusses save ~15% steel vs. Pratt

  • K-Truss can reduce deflection by 20% vs. Warren

  • Bailey bridges assemble 3x faster than conventional trusses
