Chapter 19, Problem 19.8P
For the drilled shaft described in Problem 19.7, estimate the total elastic settlement at working load. Use Eqs. (18.45), (18.47), and (18.48). Assume that Ep = 20 × 106 kN/m2, μs = 0.3, Es = 12 × 103 kN/m2, ξ = 0.65 and Cp = 0.03. Assume 80% mobilization of skin resistance at working load. (See Part c of Problem 19.7)
19.7 Figure 19.16 shows a drilled shaft without a bell. Here, L1 = 6 m, L2 = 7 m, Ds = 1.5 m, cu(1) = 50 kN/m2, and cu(2) = 75 kN/m2. Find these values:
a. The net ultimate point bearing capacity. Use Eqs. (19.23) and (19.24)
b. The ultimate skin resistance. Use Eqs. (19.26) and (19.28)
c. The working load, Qw (FS = 3)

2. Find the equivalent concentrated load(s) for the bags of cement stacked on the
dock as shown here. Each bag weighs 100 lbs and is 12 inches long. Draw the loading
conditions for each showing the equivalent concentrated load(s).
1 bag = 100lbs
L= 12 ft
L= 6 ft
L= 8ft
I have a question for this problem in the first one wouldn't it be finding the total weight of the bags which =4800lbs and the multiply that by 12ft to find the concentrated load?? but if this is the case the load would end up as lbs/ft so I'm not too sure that is right.
There are 2 parts
A) L=12ft
B) L1= 6ft, L2= 8ft
