CANTILEVER RETAINING WALLS
CANTILEVER RETAINING WALLS
(OP)
I'm designing some cantilever retaining walls where there is a slab on grade located on the heel side. This slab is a sidewalk for pedestrian use only, in fact no roads or driveways are located near these walls. I've looked at the IBC and it indicates for sidewalks to use a 250 psf live load surcharge. This values seems more likely for areas where heavy trucks are in use. Should this value in fact be used, it seems a little too conservative? Any input is appreciated, thank you.

Timing has a lot to do with the outcome of a rain dance.

In the end, you may be adding a little extra steel in the stem and you may make the footing slightly larger. As long as you are not talking about a 20' tall wall, the surcharge will not increase the sizes that much. Account for the load and sleep better at night.

Take a look at pg 94 of 592 from the link below.

The current AASHTO LFRD Specification has two tables; one for traffic perp. to the wall and one for traffic parallel to traffic. The table in the FHWA reference appears to match the table in AASHTO for traffic perp. to the wall. In the AASHTO reference for walls parallel to traffic, it only requires 2 ft of additional soil for the surcharge as long as the load is at least 1' from the wall.
