Comparing my monk with 40k dps (400 AR/4500 armor/38k hp) to my WW barb with 90k dps (300 AR/6500 armor/38k hp) monk seems to be way stronger: he gains spirit faster, is more safe to get into combat (barb could be killed in just 2 seconds while monk can simply blind everyone after 2 hits) and i almost never die. Monk's budget is way lower too. Probably killspeed is a bit slower but to my mind it's better to go without deaths and kill slower than to die 10 times in a row sometimes.
The 100 AR makes all the difference, almost as much as the armor. You also could have more lifesteal/LOH on the monk than the barb. With equal stats (for argument, both classes have 60k dps, 400 AR, 5k armor, 38k HP), the barb will outlive the monk in most situations easily.
2000 armor > 100 resist in practically every situation (use EHP calculator to verify!).
That said, though, it doesn't matter how much gold you have invested if you have it invested wrong. If your monk has good life steal and life on hit while your barb does not, no wonder your barb dies so easily. Also, are the monk stats after skill/passive bonuses? If not, then obviously he's even tankier compared to your barb that probably uses no defensive skills/passives (you really shouldn't in 1.0.5, except maybe bloodthirst). Besides, 90k DPS is quite high if you're using a stat stick off hand with low DPS, but quite low if your off hand has the same DPS as your main hand.
All stats are counted including all passives. Barb's LoH = 800 + he has LL = 2,8%. Monk's Loh = 680-ish and no LL at all. Barb's passives are WM (for crit)/Ruthless (same purpose)/Superstition (to compensate lack of resistances). I was using a mid-rolled Skorn (1300 dps/290 str/240 crit hit dmg) - the main source of my dps.
I think the biggest problem for barb is getting rage from 0 (if you die or just running a long distance from mob to mob) - 'cause i'm using a bash (Instigation) as a generator. Since my swings are slow with Skorn, if I engage 2-3 "hard" monsters they can multishot me in just a sec. With Monk i'll simply blind them all and escape or just kill fast.
TBH, the skorn might be the source of your issue. You may want to try 2x 1h weapons as you can balance stats on it easier and for less overall gold. I recently dropped war cry for overpower-crushing advance, and as long as you have the crit to back it up, you can keep up the 35% less damage taken. You can also try swapping out bloodthirst for superstition as a passive, as crushing advance covers for the loss in mitigation. I am very keen on crushing advance mainly because i can keep 100% uptime on it, and having a flat 35% extra damage reduction (in the form of a very nice reflect) is great.
I have 550 AR, 66k (unbuffed) dps, 57.5% crit, 5.2% lifesteal (8.2% with passive), 5100 armor and a little over 1100 LOH with 47k life. I did mp7 ubers tonight with some friends and never died unless everyone else died. I had no issues running through Maghda's arcane sentries if i had to get to king. Ghom never got me below 80%, and i soloed Siegebreaker to 40% while the rest of my group killed ZK. Barbs are really gear dependent to become overpowered, but they are not the most expensive to gear anymore.

Blizz has said multiple times that they would rather buff than nerf, but they do the opposite.
