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)

: A 5ms- long current pulse is desired for two linear lamps connected in
series and pumped at a total energy input of (1KJ). Each of lamps has
an arc-length of (10cm) and a bore of (1cm). If we assume a peak
current of (i, -650A). Design a multiple mesh network including
number of LC sections, inductance and capacitance per section and
capacitor voltage.
