Name: Score:47 Multiple choice questions
Term 1 of 47
Why do we not want differential settlement?
Foundation can crack due to height difference pulling it apart in tension.
It allows for better drainage around the foundation area
Differential settlement helps in creating a more stable foundation
Differential settlement is a method used to strengthen foundations
Definition 2 of 47
horizontal, downward, or even upward pressure
seismic loads
live loads
dynamic load
wind loads
Term 3 of 47
earth and water horizontal loads
soil bearing pressure
fluid pressure
hydrostatic pressure
gage pressure
,Term 4 of 47
How much does concrete typically weigh per cubic foot (ft^3)?
110-150 lbs per (ft^3)
cement, large aggregates (gravel), small aggregates (sand), and water
no basement, no basement walls, just one slab of concrete on which you build your house
the trenches for the footings
and for the plumbing are
excavated, the plumbing
installed and then the slab and foundation are poured.
sands and gravels
silts and clays
peat and topsoil (non-structural - no bearing capacity)
Term 5 of 47
light framed construction
foundation and columns are separated by rubber bearings
Used in areas of the country where earthquakes are common
base isolators flex or yield to absorb a significant portion of movement during a seismic
event
Light framed building foundations must reach through the unstable organic soil to stable
undisturbed soil beneath the local frost line.
Undisturbed soil is more solid. The local frost line protects concrete from cracking due to
freezing and thawing.
Loads that CAN move, including loads that change in magnitude and/or direction along
with loads that can move along a structure.
you must find some way to stabilize the soil or foundation or the structure could collapse
, Term 6 of 47
shallow foundations on spread footing
Spread footings are designed to be above ground for better visibility
Spread footings extend below all organicmatter and the local frost line to supportthe
foundation walls
Shallow foundations are only used in areas with high seismic activity
Shallow foundations are primarily used for decorative purposes
Term 7 of 47
types of soil testing for bearing capacity
penetration test, test boring, test pits
hydrostatic pressure
vaults or a-frames for example
Foundation can crack due to height difference pulling it apart in tension.
Term 8 of 47
Poor Bearing Conditions
you must find some way to stabilize the soil or foundation or the structure could collapse
you can simply add more weight to the structure to improve stability
you need to enhance the aesthetic appeal of the building instead
you should ignore the soil conditions as they do not affect the structure
