HiAs i understand, in every cut-cover project piles are built as a primary strucure and its capacity after construction of final lining (final structure) is ignored.
does any one has any experience to account for long-term capacity of piles for contribution in long-term load carrying capacity of final structure?
Hello Ahmad,
One comment I have about a common misunderstanding is about changing the stiffness while no other change is applied on the model. Please check the following article and take it into consideration: https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision-wiki/45962/reduction-of-stiffness-does-not-lead-to-a-change-in-displacements
HiI think you wanna tell that if we want to consider "degradation" or somehow apply possible loss of concrete strength, we should decrease "strength" and lowering down just "stiffness" leads to almost nothing.am i right or you wanna say sth else?and an important question about main topic (considering temporary structure long-term load carrying capacity) is how much you could count and is there any limitation for example?
Dear Ahmad,
To be precise if there is no out-of-balance to be solved, any change in the structural materials will not create the development of deformations.
For the temporary structure long-term load carrying capacity, I believe that this is an engineering decision and not something anyone without knowing more details about the project can answer with 100% certainty.
