Abstract:
Considerable thermal gradients exist in nuclear reactor pressure vessels. This paper presents the results of experimental studies on the effects of creep at elevated temperatures on the relaxation of stress and on the amounts of deformation in flexurally restrained prestressed concrete beams.
