Officials in Vienna say he dropped the bag and tried to flee on foot when he triggered metal detectors at the entrance.
The suspect - described as a 42-year-old Bosnian who now lives in the province of Lower Austria, which encircles the capital - was arrested nearby and taken into custody around noon local time.
No-one was injured but police sealed off the area as a precaution, patrolled with bomb-sniffing dogs and shut down or rerouted nearby bus and tramway lines.
A police spokeswoman said: "There were a lot of nails in that bag. Had it exploded, it would have had an enormous shrapnel effect."
