I find adding stringers and ribs to the inside of aircraft models frustrating; it is difficult to handle small strips of plastic and get them into position before gluing. Here is an idea that simplifies everything: Microscale Micro Bare-Metal Foil adhesive.
I apply foil adhesive to one side of a styrene strip. When it’s dry but tacky, I cut the strip to the length I need and attach it where it needs to go. The glue is strong enough to hold the strips, but you can still reposition them if need be. Once you have the strip in its final location, I run a bead of liquid cement along it to permanently attach it.
