Passive pressure for a retaining wall + expansion joint
Passive pressure for a retaining wall + expansion joint
(OP)
1 - When dealing with the design of a retaining wall, why some engineers prefer not to mobilize all the passive pressure ? Is there any rule or it is just a way to be conservative ?
2 - if the retaining wall is long enough in plan and an expansion joint is introduced every interval, does the expansion need also to be in the foundation ? A shrinkage strip will delay the construction so 2 remaining choices : expansion joint, or additional reinforcement to catter for shrinkage effects ?
Thank you

RE: Passive pressure for a retaining wall + expansion joint
NYSDOT places contraction joints in the stem every 30' and an expansion joint through the stem and footing every 90'. I've gone a further with the expansion - a little over. 100' feet - with no ill effects.
