CRJ200 captain; on a downwind vector for runway 23 at crw and descending to 3;100 ft; experiences a ...

Narrative:

While being vectored for an ILS to runway 23 in crw; we received a terrain warning. On the downwind leg (approximately 5 miles abeam the runway) our clearance was to 3;100 ft. The altitude was confirmed set in the altitude alerter. During the shallow descent approximately 900 FPM and almost level at 3;100 ft is when we received the alert. Minimum vectoring altitude for this sector is 3;100 ft according to the approach controller. Responding to the alert; we climbed to 3;700 ft and the alert was extinguished. At that time we alerted the controller of our situation. We were then vectored for a base leg and the approach continued without incident. No known error was made by the crew and all standards and procedures were followed to the best of our abilities. Crew had been on duty 14 hours at the time of this incident. Multiple aircraft swaps due to maintenance during the duty period. This duty followed a 12.5 hour shift the previous day with 9 hours on the ground. [Suggest] scheduling with safety and common sense in mind.
