Hi! I am currently working with settlement in shallow foundations, and we need data on some "If" values (depth correction factors) for analysis - I've searched all around, and got to MITTAL's paper and even to the original FOX's paper for his equations - however, I wasn't able to achieve the same results when trying to apply his formulas in softwares such as matlab or excel, due to some factors:
- On his final table, ( page 6 for reference), Fox specifies ratios for L/B and Df/B - however, we couldn't quite point out which data he used to achieve these results. For example, there are many possible values for L, B and Df that might result in a same value for the L/B and Df/B ratios. When applying his formula, I find many different results for different values used, but we could never quite reach que same result as the table/chart.
- We can't quite figure out if we might be making a mistake when writing his formulas down on the software -
These are some threads I've visited when researching - I've found some programs but I couldn't figure out how to run them, although I've tried to run some c++ compilers before; the install file just won't seem to run on my computer. Still trying to figure out if I might be able to run it somewhere else.
thread256-25162 This is an older thread from someone who was also searching for a spreadsheet model for Fox's equations - However, I couldn't find a way to contact the people who could have them
I'm aware of other authors that have worked with Fox's values such as Mittal, Mayne and Poulos and many others - however, for precision reasons we need to pinpoint Fox's equation results necessarily. Is there any paper or program I can reach to find help with that?
In advance, I apologize if it sounds confusing - my english is a bit rusty, but I'm happy to explain it further if needed.
- that is a printscreen from my matlab running and some of the formulas I'm trying to use.
- that is Fox's article with his original formulas, which we're trying to apply for a number of different B, L and Df combined values for analysis.
