The pool is approximately 5’ from the wall. With reference to the below calc and figure, the geotech seems to be treating the pool as being lighter than the soil it displaces, and accounting for the surcharge by treating it as a “failure wedge” for a 1:1 sloped backfill condition, resolved into...
The recommended EFP for this application is actually 48psf/f, due to the presence of an in-gound swimming pool above. You are correct that the higher allowable bearing stresses above 2.0ksf will come with additional anticipated settlements, per the geotech ( I am awaiting his amended...
Yes. To clarify, the suggestion from the geotech is to take the average of a 4.0 ksf, triangular reaction stress, and call that 2.0ksf average across the base of the footing, if I am understanding him correctly.
Neglecting seismic, my retaining wall footing sizes become unwieldy for retained heights around 8' and up. Using 30pcf EFP, it's not unusual to see these footings grow to a width of 6'++ for toe under type walls. I spoke with a well seasoned soils engineer recently who is encouraging me to use...
Replying to responses provided thus far:
Composite decking and steel might be feasible, however I still question the stiffness of such an assembly.
As the space below is a large theatre/recreation area, there is no option for intermediate walls, or posts.
There is minimal 4’ setback sideyard...
It is proposed to utilize a concrete lid over a residential basement, approximately 20’x40’, which can be used as a sport/pickle ball court. I do not have any guidelines for this type of application. My question here relates to adequate stiffness to accommodate the activities above.
Thank you...
