Thank you gargarot89, this helped me on my journey.
I eventually discovered the answer to my problem courtesy of Dr. Franke's YouTube channel.
The issue was one needs to add pi to the equation when (mn)^2 > m^2 + n^2 + 1. See youtube channel link below at 15:40 for those that find themselves...
Thanks for the sanity check fel3,
Does anyone happen to know the limitations of this equation or if Das was wrong with the integration? I did a parametric study and plotted I vs m for varying values of n which seems to show almost a phase shift once values of m and n become greater than about...
Does anyone have a closed form equation for Boussinesq surcharge below corner of a rectangular area? I'm struggling to get the closed form solution provided in Das Equation 9.35 to mach the results on the curves shown in Figure 9.24 for m=2 and n=2. Please see page 3 of the attached pdf...
Helping to Design excavation support wall for commercial basement excavation in USA that will also support some decking for construction equipment and utility supports. Does anyone know of good reference material out there with regards to calculating the vertical capacity of tangent piles or...
I'm looking for the closed form equations that describe the correlation between "Phi/Relative Density vs Initial Modulus of Subgrade reaction" shown in the attached graph. I got this from the following source...

Hey Mike,
Thanks for the reply. I have checked all the drawings that I could come by and don't see any note or geometry indicating brackets on the piles. Are you thinking of Helical Piles maybe?

I recently worked on the consulting side of a DOT Sound Barrier Wall project. Typically the objective of these projects is to tell the designers if the soils meet the standard specs for their (DOT) pre-engineering structural designs (N=X, Phi>X Gamma'>XX.X pcf). If not, provide Geotechnical...
I understand that the SPT "N" values are corrected for both hammer efficiency and overburden. According to my Foundation Engineering textbook (Das), the overburden correction is only performed for sands. I was curious if anyone can explain why overburden affects the N value correction for sands...
