The flashcards below were created by user porgitech on FreezingBlue Flashcards. What would you like to do?


  1. Live Load
    the weight the users bring into the building

    this includes: furniture, equipment, etc.
  2. Dead Load
    the weight of the building
  3. Lamella Truss
    A structural web with a repeating identical diamond pattern

    Jigs or templates are often used

    It transfers the load to the ground

    Temporary supports are used at the beginning

  4. Rain/Snow Load
    the load created by rain/snow collection on the roof
  5. Wind Loads
    create pressure from all different diretions (including upward and downward)

    • -Pile Drivers
  16. Migration through the soil of ______ must be managed.
    Water
  17. Types of Foundation
    • -slab in grade, reinforced trench footings; there has to be footing below the frostline (this is the most basic type of foundation) 
    • -shallow foundations on spread footing
    • -crawl space with spread footings and short foundation walls
  18. Benchmark Elevation
    ***COME BACK TO THIS
  19. Steel Form Work
    utilizes steel wedges and form ties which keeps it from blowing out
  20. How do you anchor a building to the foundation?
    -anchor bolts through the plate (sill seal is used to keep out water)
  21. Retaining Wall Failure
    • 1. Overturning
    • 2. Sliding
    • 3. Undermining
  22. Drip Line
  23. Softwoods
    Evergreens
  24. Hardwoods
    Broad Leaf
  25. FSC
    Forest Stewardship Council

    -3rd party that ensures that the growth and harvesting of forests is sustainable.
  26. How do you season lumber?
    • -must be dried to prevent shrinkage and distortion
    • -can be done by air-dry or heated in a kiln
    • -generally lumber has 3-% moisture, but needs to be at 19%
  27. Green Lumber
    lumber that has just been cut down
  28. Pressure Treated Lumber
    -a process that forces chemical preservatives into the lumber to create lumber that is resistant to rot and insects 

    • -CCA: old, harmful, no longer used
    • -ACQ: new, currently used
  29. What is a deciding factor when selecting lumber for a project?
    -some lumber can touch the ground(earth) and some can't
  30. Types of Engineered Lumber
    • -Plywood
    • -OSB
    • -Particle Board
    • -Fiber Board
  31. Gluelams
    large beams made up of dimension lumber and often left structurally exposed in buildings
  32. Paralams
    structural beams stretching from load bearing point to load bearing point

    (equivalent to OSB)
  33. Microlams/Laminated Veneer Lumber (LVL's)
    • -often used from smaller beams 
    • -made of wood veneers (similar to plywood)
