摘要
将最新规范规定与最新科研成果相结合,运用高等数学中定积分的理论,推导出疲劳裂缝扩展寿命与疲劳荷载循环次数及此时预应力筋应力之间的关系,从而确定构件破坏时几个重要参数之间的理论关系。
Combined up-to-date code with latest achievement in scientific research, the author deduces the relationships among the extending life of endurance crack, cycle index of endurance load and stress of tendon by using definite integral theory in high mathematics, in order to confirm the theoretical relationships among several important parameters when the member is being damaged.
