I am having trouble defining a parameter used in a lateral load chart for
short piles developed by Broms, 1965. The chart is shown as Figure 19.61 in
the Foundation Engineering Handbook, edited by Winterkorn and Fang,
published by Von Nostrand Reinhold, 1975.
The parameter is listed as lambda sub P (I spelled it out since I can't
show it correctly in this email). This is a factor in the lateral capacity
for piles in cohesionless soils.
There is a lambda definition shown several pages earlier in that chapter
(Equation 19.18)
The equation is:
2 tan (phi) tan (45 + phi/2)
Can anyone confirm if this is appropriate for the lambda sub P definition?
