allowable deflection in soldier pile ret. walls
allowable deflection in soldier pile ret. walls
(OP)
what is the allowable deflection in a hp-soldier pile retaining wall.
as per the IDOT standards, the deflection shoulw be less than 1"? is this a MUST?
any suggestions as to what is an accepectable limit for deflection?
i have used the software ALLPILE to determine the deflection, based on multiple soil layers. i did find a bug it in
any other softwares?

As for software, I have always used a spreadsheet for analizing walls.

Another thing to consider is how do you compute deflection. Pressure envlopes are an approximation, and the point of pile fixity is often somewhat arbitrary. We can relatively easily compute capacities of wall systems, but deflection predictions are more of an estimate.
If you are putting out specs for design build wall systems, The reviewer should be able to see the estimate of wall deflection. Rather than limit the deflection to an arbitrary criteria, I would suggest making deflection calculations and the designer's comments on the effect of the deflection a required part of the submittal.
Good Luck

my bad, i had given incomplete information.
i have proposed a soldier pile retaining wall for a channel section. the retaned ht is approx. 10-12 ft.
when sat. soil condition is considered behind the ret. wall.. the deflectin is abt 4" which is unaccepectable.
in some sections \the soil behind the wall is sand or silt...under these conditions hydrostatic pr behind the wall is not an issue...and then the deflection is around 1.2".
so my question was pertaining to what is an accepectable deflection limit?
the bending stress in the H piles is not an issue.(it is well within the limit).
thanks again for the replies.

As for programs, "Allpile" is a pile program from Civilsoft. They also make "Shoring" which computes loads and deflections for earth retention systems and would be more suited to your situation. Another program is SPW 911 from Pile Buck. This program is also designed specifically for earth retention
