「イライラする」：feel frustrated
「仕事に集中する」：concentrate on work
When you're frustrated or annoyed by something, it's difficult to concentrate at work. To convey that, you just need to say that you're frustrated (or annoyed) by something and, as a result, you can't concentrate on your work. "I'm frustrated and can't concentrate on my work" or "I'm annoyed and can't concentrate on my work" are both fine. If you want a synonym for "concentrate", try "focus." "I'm frustrated/annoyed and can't focus on my work."
"frustrated"（いら立った） や "annoyed"（イライラした）していると、なかなか仕事に集中できません。これについて伝えるなら、イライラしていて（frustrated / annoyed）、その結果仕事に集中（concentrate on my work）できないと表せます。
