Elevated temperature creep model of parallel wire strands

Frontiers of Structural and Civil Engineering Pages 1060-1071 doi: 10.1007/s11709-023-0981-y

Abstract: Under fire conditions, significant creep effects occur, reducing the prestress and influencing the mechanicalAs there is no existing approach to analyze their creep behavior, this study experimentally investigatedthe elevated temperature creep model of PWSs.It was concluded that the temperature level had a more significant effect on the creep strain than thestress level, and 450 °C was the key segment point where the creep rate varied significantly.
