Continuative or repeated efforts and fatigue

[Astral Wanderer]

I thought I remembered rules for continuative or repeated efforts, such as repeatedly trying to bash a door, push/pull a boulder, and other things like these, but now I can't find any.
Alright with the rules for forced march and all the rest, but what about the above? Is there any rule? And if there isn't, how would you rule it?

DM fiat. I suggest looking up the rules for a forced march, and using that as a guideline for your own house rule.
