Building construction
Show Answers:

  1. What a load?
    its a force acting on a member or structure
  2. What kinds of loads can a structural member experience and what can that create?
    • Axial
    • eccentric
    • transverse
    • torsional

    • creates
    • tension and shear forces resulting in stresses
  3. What are the 3 kinds of loads?
    • Dead- permenently in place items or structures
    • live- occupancy objects that can be moved
    • snow and wind
    • seismic- eg earthquakes
  4. FYI- master stream delivers 4700 l/min and that translates to a load of up to 4700 kg/min added to a structure
  5. what is the typical safety factor for a building?
  6. What are collumns and what are the 3 types?
    • A column is a structural member that transmits axial compression loads
    • 1 piers or compression blocks
    • 2 short or intermediate
    • 3 long or slender
  7. What is a beam? 3 types?
    • structural member that carries loads acting in a direction which is transverse to the longitudinal axis of the member
    • 1 simple supported at both ends
    • 2 continuious supported in 3 or more locations
    • 3 cantilevers rigidly supported at one end and project over a support point on the other
  8. What is a truss?
    framed structural member that utilizes a triangle or group of triangles in a plane to carry transverse loads.
  9. What are the kinds of trusses (9)?
    • Bowstring
    • flat
    • gambrel
    • inverted king
    • inverted queen
    • kingpost
    • mono
    • cuttoff
    • room in the attic
  10. what are the three types of building materials?
    • Non-combustible
    • combustible
    • fire resistant
  11. what is considered a high rise building?
    • over 36 meters
    • or over 18 meters with a high occupancy to egress formula ratio
    • two types concrete + steel
  12. What are low rise?
    low rise and industrial are general terms that cover buildings that are up to aprox 6 stories difference from high rise is reduced code req. for fire resistance.
  13. what are the 3 types of roofs?
    flat, pitched and arched
  14. the 6 types of pitched roofs?
    hip, mansard, lantern, shed, gambrel, gable
  15. What is the spotting zone when parking apparatus by an involved structure?
    Allow for a collapse zone of 1.5 times the height of the building
