Forces: Tension and Compression

Structural Analysis

Every bridge must balance two primary forces: Compression (pushing together) and Tension (pulling apart).

Bridge Types & Forces:

  • Suspension Bridge: Main cables are in high tension; Towers are in high compression. Best for long spans (e.g., Golden Gate).
  • Arch Bridge: The entire structure is in compression. The force is transferred outward to the abutments.
  • Beam Bridge: The top of the beam is in compression, bottom is in tension. Limited span length.

Load Distribution

Dead Load vs. Live Load

Engineers must calculate two types of loads to prevent structural failure:

  • Dead Load: The weight of the bridge itself (concrete, steel, asphalt). This is constant.
  • Live Load: The weight of traffic, pedestrians, wind, and earthquakes. This is variable.

Exam Prep: Make sure you can calculate the 'Moment of Inertia' for simple beam designs. High MOI = less bending.
