## Cantilever Sheet Pile Wall With Wind Load

## Cantilever Sheet Pile Wall With Wind Load

(OP)

Hi Everyone,

I am working on a project in which we are to install a cantilever sheet pile wall as per the attached. The wall occurs next to a body of water. I have performed the design of the wall accounting for all lateral earth pressures and hydrostatic pressures. The one thing I am struggling with is the inclusion of wind loads on this structure. The wall continues above grade about 4' and a 7' tall chain-link fence is applied on top of this. I have designed a channel cap to span along the top of the wall so that the wind loads imposed by the fence posts load the wall relatively uniformly along the wall's length. In terms of analysis, are there any techniques which are commonly used for this condition? I am trying to not go beyond the pile depth shown, and am near capacity on my pile design. I just don't know if the wind load will control given the amount of soil being retained. I am assuming the traditional ASCE7 load combinations apply as per usual.

Any help or feed back would be greatly appreciated!

H + L

H + 0.6W

H + 0.75L + 0.75(0.6W)

where

H = lateral earth pressure

L = lateral earth pressure due to surcharge

W = ultimate wind load

Most of the time, H + L governs. Wind is generally not a concern with sheet pile walls, because nothing is exposed to the wind above the upper grade (and as far as I know, nobody bothers to check suction on the wall itself). But you have an unsual case, where the fence is actually taller than the cut.
