thank you!
although i knew this (but not the reason behind) one can not find it in the ACI code and it is hard to imply this to ignorant people. any official written document for it?
i want to know if it is mandatory to check 6/5 beam to column capacity control in the last floor of the building. because in the last floor, the joint only has one column and normally two beams and it is hard to satisfy this issue. you will need a bigger column (in size or reinforcing) compared to below floors.
is there any exception for the last floor? (working with ACI)
