| 摘要： | High-strength concrete can be used to achieve longer-span or more widely spaced prestressed bridge girders. Two full-size long-span, high-strength prestressed bridge girders were constructed to investigate the effects of high-strength concrete on transfer length, camber, prestress losses, fatigue, flexure, and shear strength. The results of studies on constructability, transfer length, prestress losses, and camber are presented. |
