Dear Joe,
This involves many details and arguing opinions of Tanaim, Aamoraim, and Rishonim. First learn Eruvin 94b, also thegeneral introduction of Artscroll to Eruvin, chapter 2- Mechitzos.
Gud Achis can lower a hanging partition- however there is the problem of Gediyim Bokin
Pi Tikra doesn't always work. It has to be flat-horizontal. Also it depends if it is in the street, Karmilis, or Yachid. Also, how many sides need Pi Tikra? How wide is the opening? 10 Amos or more?
Tzuras HaPesach also depends. See Shulchan Aruch 362:10 at length.
B' hatzlacha All the best,
Reuven Weiner
