How does water in the granular backfill in the wall change
/affect the design of an MSE wall?
a) Unit weight of granular fill
b) Total overturning/sliding forces
c) Corrosion rate of reinforcement
d) What would be your choice of soil behind the wall to minimize
water-related problems.
Calculate the static active earth pressure and seismic-induced
earth pressure increase for a concrete retaining wall with the
back-wall angle β of 10o with the following given
conditions:
Wall height: 8 m.
Backfill density: 1.8 g/cm3.
Backfill angle of internal friction: 36o.
Concrete wall back and backfill interface friction angle δ:
22o.
The wall is located at a seismic zone with design seismic
coefficients: kv=0.12 (vertical direction) and
kh= 0.36 (horizontal direction).
The soil below wall base is strong enough...
How does a crack grow and why does the mean stress level
influence the rate of growth within a metallic component? Is this
material specific and if so explain why? Include how maintenance
can influence the ‘life-expectancy’ of an aircraft.
(Fluid):-
Density, Specific weight, Specific gravity, Salinity,
Compressibility, Vapor pressure, and Surface tension:
Explain how these properties might explain the behavior of a
fluid, or explain something you observe every day
please give one brief sentence for each.
Briefly explain how each of the following would likely affect
the value of the dollar and the exchange rate, all
else being equal. (Please answer for all 5!)
1. U.S. consumers increase their spending on imported goods.
2. The Federal Reserve reports that it is less concerned about
inflation and more concerned about the impending recession in the
United States.
3. The U.S. government imposes a large tariff on imported
automobiles.
4. The Federal Reserve raised interest rates fearing
inflationary...
