ABSTRACT
Example 15. 7 Determine the base load of the problem in Example 15.1 by Janbu's method. Use VI = 90°. Determine Q
a for F
s = 2.5 using the Qfestimated in Example 15.5.
Solution From Eq (15.31), for c = 0 we have
, N *qb = qo q For l/J =30° and VI =90°, we have Nq* = 18.4 from Table 15.1. q~ = 262.5 kN/m2 as in
Ex. 15.5.
