Design Principles of Expansion Joint Systems in Buildings, Plaza Decks, Parking Structures and Stadiums

Outline/Agenda of Interactive Learning Activity

  1. Traffic & Service Conditions Dictate Design
    1. Type and Speed of Traffic / Service Conditions
    2. Waterproofing / Movement Considerations / Aesthetics
    3. Temperature Adjustment Principals
    4. Concrete Construction
  2. Design and Selection Criteria of Expansion Joints for:
    1.  Types of Structures – precast, post tensioned, tilt-up, etc.
    2.  Coefficient of Expansion – static vs. dynamic movement
    3. Direction & Amount of Movement – thermal, seismic, lateral shear.
    4. High Volume Areas – entrances, bridges, walkways, parking, etc.
    5. Heavy Loads / Service Conditions – cars, buses, delivery trucks, fork trucks, snowplows, cleaning equipment, etc.
    6. Pedestrian Safety – ADA compliance vs. trip hazards
    7. Life Safety – fire rated designs
