My current plan is that since for walls of that height sliding is usually the controlling factor, design the wall to meet the overturning criteria and use dowels into rock to provide additional sliding resistance. That should give me 2 or 3 feet on heel length and make it thickness more reasonable.
Thanks for you help, Mike. Unfortunately the client is adamant about keeping the room below the roadway, which is supported by the wall, clear of any possible future utility installations (it's a city street). A modular gravity wall as well as tie-backed walls have already been suggested as a...
It's still one of the options on the table, I'd like to avoid it though. Too much formwork over 450+ feet of wall, which may raise the unit cost and negate any advantage in material savings. The construction time is also quite limited.
The problem is actually the opposite - I can not use a toe due to R.O.W. restrictions, so the heel is very long and therefore needs to be very thick and with a lot of reinforcement.
I have a tall (30') cantilever concrete wall which is to be founded or rock. Normally, for this type of retaining wall, the heel is designed as a cantilever supporting the weight of the fill and any additional surcharge to account for possible tilting. Is this design requirement still valid for...
"civilperson", "jdonville", thank you for your replies. I guess there is a little confusion in nomenclature. It is really a mini-pile with its top portion encased in steel to provide moment resistance. I will probably model it as fixed since that gives me the most conservative pile loads (the...
I am currently analyzing a pile cap with 12.75" diameter bored-in piles. The embedment of the pile into the cap is 12". Since no dowels are provided except a central core rebar, is it a valid assumption to assume that the pile is pinned? The foundation is subject to very high lateral loads...
