Frontiers of Structural and Civil Engineering 2012, Volume 6, Issue 3,   Pages 297-307 doi: 10.1007/s11709-012-0162-x

Abstract: In the past, for simplification, creep behavior was not taken into account in research on the resistanceHowever, it was demonstrated that the effect of creep is considerable at temperatures that commonly reachThe geometric nonlinearity, material nonlinearity, high temperature creep, and temperature rate of changeFurthermore, it is demonstrated that the deflection at the midpoint of the steel beam, considering creepbehavior, is approximately 13% larger than for the situation in which creep is ignored.

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.
