Prediction of surcharge (lateral pressure) from existing buildings and/or traffic.
Prediction of surcharge (lateral pressure) from existing buildings and/or traffic.
(OP)
All,
Can any body suggest me some good references or info about "how to predict surcharge ( for lateral pressure) from existing buildings and/or local traffic" that can be used for tie-back shoring wall design?
No of stories of the building and street location are known.
Thanks a bunch in advance.

RE: Prediction of surcharge (lateral pressure) from existing buildings and/or traffic.
For the building, I would calculate the dead load plus a reasonable assumption for live load (since you have a multi-story building), and divide by the building footprint to determine a surcharge. But if you have isolated footings very close to the wall, you should use the calculated bearing pressure under the footings.

Thanks for the info.
Unfortunately, I don't have any information about the dead & live loads for the building. All I know is no. of stories.
Can you suggest some references or info to approximate these loads. I don't want to be too conservative and its a temporary shoring, may be for 6 months max.

My experience: For buildings over 10 floors, use 15-20 kPa per floor, if you do not know the raft thickness, assume a thickness and multiply it with 24 kN/m3. For below 10 floors, use 10-15kPa + raft thickness*24.
