Abstract

The pretightening force of FRP construction bolt joint has been researched in the theory of bolt washer stress. The computed pretightening force of bolt and washer size reach the prefigurative result in the construction test, but the pretightening force of bolt was decreased obviously by the time increase for matrix relaxation effect, and then tending towards a stable value.
