Is there any way to add your strength modifier to AC? I know there is a way to add every other ability modifier to AC but I don't know one for strength.
I don't think so. And I don't think there is anyway to get con instead of dex on AC.
Monk can add WIS, Duelist PrC can add INT (= class level), what adds CHA without replacing DEX or WIS as an untyped bonus to AC?
There was a feat in 3.0 "dashing and daring" that let you add your cha to AC against opponents that weren't mindless.

I am not sure that the point was 'without replacing DEX', so oracles fill the cha-based AC niche. Additionally paladins do, whenever they smite.
Oracles, far as I am aware, do not get to apply both Dex and Cha to their AC. The claim was made that there are ways to apply Dex, Int, Wis *and* Cha bonuses to AC.
Paladins' bonus is typed (deflection) and situational which does not fulfill the criteria.
Sidestep Secret (Oracle of Lore) and Nature's Whispers (Oracle of Nature) *replaces* Dex with Cha for AC which does not fulfill the criteria.
Criteria from the OP: "...there is a way to add every other ability modifier to AC...", which is what I'm asking about. Oracle and Paladin do not do this, not as I understand it.
No str to AC...
How would it work? A bare-chested barbarian who is so excessively muscled that blows glance off his well-oiled, bulging biceps?
I'd require wearing no armor at all for an ability like that.

Nobody claimed it was possible to get all of those to AC simultaneously, just that it was possible to get any of those to AC.
No official rule that I know of.
To do it though I'd have a suit of platemail magical made so dense as to make it extremely difficult to get through. It would be 9 AC and no dex bonus but ever point of strengh would allow you to add 1 to the AC. The armor heavy but if you you move it you can better protect yourself.
I'm not sure what I call this magic quality or how much it would cost though.

Osyluth Guile adds CHA as a dodge bonus when fighting defensively or total defense. With this feat, a monk going into Duelist could get DEX, WIS, INT, and CHA to AC, and it would work nicely with Crane Style for even more AC. Not that you could get a monk with good scores in all those ability scores without magic in a point buy system, but it could still be theoretically done. Nice for people that roll really good stats at least. *edit* Ah, someone already said this.
With that feat, I can see someone doing something like feints (not the maneuver but general deceptive movements) to trick the opponent into hitting the wrong spot. But adding STR? "I get my STR mod as a shield bonus by flexing my biceps"
Strength adds to your carrying capacity.
Armour is heavy.
Strength adds to your AC by means of a shield or heavy armour.
There were several ways to add Con to AC in D&D 3.5. Solo's hilarious Barbarian guide ("Being Bane") referred to it as "blocking with your chest!" :)
I think Str to AC should be possible. You would use shield or large bracers over the forearms to block attacks with, perhaps. But that would be houserules/creations.
For RAW PF, there's nothing. Your best bet would be finding a way to make certain attacks, or as many kinds as possible, target your CMD rather than AC. CMD is a str-based defense, after all.
