rim strength question
i have a bicycle that has V-ish rims designed for us solely with disk brakes.
are square rims meant for use with caliper-type brakes (though heavier) altogether stronger too??

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

It isn't the overall shape, square vs. "V" that determines whether the rim is suited for rim brakes or not. It's whether it's designed with a braking surface. Disc/Drum/hub brake rims don't need flat sides for a breaking surface nor have extra material there to provide for wear. rims made for caliper brakes need both.
You can always use a rim brake rim, with a hub brake, but not necessarily the other way around.

I've been told that, all other things being equal, a rim with braking surface will be less laterally strong than a rim without, due to the higher amount of completely vertical material that the braking surface brings. Of course, all other things are seldom gonna be equal. Best way to select a strong rim is to decide what parameters you *need* (style of brake to be used, if you have a hub in mind already, how many holes do you need {if no hub yet, the more spokes, the stronger, all other things being equal**, width of tires you intend to use, etc), and then do some research as to which rim that fits your needs is best known for bombproof durability. Of course, any trade-offs you make in regards to weight is entirely up to you.
I have some salsa gordos, 36h, laced to shimano lx hubs that have been thru a lot, several years under a fat man, and only needed a very small amount of truing over the years... That's my vote for a rim-brake rim, although there are many others out there to rival it.

In no particular order...

I don't even understand the question. But, if you search my posts, you'll see a thread where I asked whether a wheel for a disc brake could take a V-brake. Also, if you want strength, touring rims can be strong.

AEO has a good list. One thing to equalize the comparison is weight, you must compare V-shaped of the exact same weight of box-section. Otherwise you'll have a 4-way comparison. For strength, I've found the Sun Rhyno Lite rims to be among the strongest out there. It's used by pro downhillers and BMX riders. Able to take 8-10ft drop-offs and jumps without any problems.
