Complete Solutions UPDATED!!!
Correct
Incorrect
For ice loads, ice density must not exceed what?
Workability γ= 56 pcf
Fr = (3PL/2BD^2) Toughness
,For wood design, part 4 of the NDS is about what?
Sawn lumber:
-Dimensional Lumber: any material that has a nominal thickness, 2-4". (i.e. less
than 5")
-Timber: Large size members. Minimal nominal dimension is 5".
- Decking or Boards
a.) Liquid Limit
-Liquid limit represents the water content that corresponds to transitioning from a
plastic state to a liquid state. It is the maximum water content any soil can go.
Temporary structures used to support incomplete structural elements during
construction of the permanent structure.
(I.e. shoring, bracing, formwork, earth-retaining structures)
-A stabilizer or retarder that essentially stops the hydration of cementing materials
- An activator that re-establishes normal hydration and setting once added to the
stabilized concrete.
,What is the equation of a determinate truss?
- The result is a denser soil that is more representative of the compaction densities
that can be achieved with modern equipment.
-5 layers of soil
-25 blows
-10 lb hammer
-18" height
- The curve is always lies above and to the left of the standard proctor curve.
Uniformity
Where the increase in force correlates to the stretch of the material in linear portion.
Once the force is relieved, so is its strain, and the material returns to its original
shape.
M + r = 2j
, moment of interia equation
a.) Φ
ACI 19.2.2
c.) β
Pm = PgIs <= 20Is
I=Ii+Aid^2
(ASCE 7.3.4)
(T/F) The envelope procedure is applicable to all building heights and
enclosure classes
False
- That would be the directional From where the wind is coming from
procedure
