concrete encased soldier piles: composite behavior
concrete encased soldier piles: composite behavior
(OP)
I am designing a retaining wall using concrete lagging and encased soldier piles. The concrete encased soldier piles have channel shear studs over the depth of embedment. I want to utilize the composite action in order to reduce the design moment and hopefully bring down the weight of my H piles. Any insight would be greatly appreciated :)





RE: concrete encased soldier piles: composite behavior
Precast lagging is always tough to install for anything other than a cantilevered wall which can be built in an open cut, sloped excavation. If the wall is higher and is tiedback, you will have problems with the precast and the tiebacks. These problems being coupled with encased soldier beams, you should have your hands full. You are braver than I am.

If you want to bring down weight, why not increase the size of the member and gain greater Inertia. Hopefully you don't have a restricted site.

I suspect that heavier steel soldier beams will be cheap compared to the cost of the other details. Do a search for other threads about the use of precast concrete lagging. It has been discussed several times.

It sounds to me like you should put this out as a design build project for qualified retaining wall contractors. Give them the soils information, wall height, and wall length and let them complete the design and construct the wall.
