摘要:Under the action of natural freezing-thawing cycles, static force loading and fatigue loading tests on four simply supported beams were conducted. Various indexes of the beams such as stress, deflection and crack at each stage of loading were recorded; a comparative analysis on prestress loss of the beams was conducted, based on which a formula of relationship between freezing-thawing and prestress loss under fatigue loading was established.
