Analysis of Surcharge on Concrete Wall

[Deadblow]

Hello All,

I need to analyze how a large surcharge will act on a 6'-8" tall poured concrete wall with a slab on the top (analyzed as a basement wall). The surcharge comes from a silo that will be resting on the concrete slab. The weight of the silo divided by its area gives a 2,044 psf surcharge. To calculate the pressure that this puts on the wall, I think I should just take (at rest earth pressure coefficient)x(surcharge)x(height of wall) and apply that load at mid-height of the wall. Does this sound accurate?

Thanks

My experience is in construction engineering where we will usually have a high surcharge from heavy equipment (typically a crane) next to a retaining wall or something of the sort. We use CALTRANS Trenching and Shoring Manual, you could conservatively assume it's a point load and use Boussinesq equations to determine the surcharge. Or assume a distributed load as well an apply the Boussinesq for that instead,

Thanks for the input. I downloaded the manual and will follow its guidelines.
