measured stress

This paper establishes the fatigue stress spectrum of the transom and the bottom chord of a bridge over the Yellow River based on the measured stress and confirms the residual fatigue life by using mathematical model of existed steel bridge fatigue life.

以黄河某大桥的实测应力为基准，建立其横梁、下弦杆的疲劳应力谱，并运用既有钢桥疲劳寿命的数学模型确定其剩余疲劳寿命。

Measured stress in and after construction process is consistent with theoretical stress. It has stress reserve checking up with theoretical results that satisfies designing requirements. So it achieved the aim of monitoring.

施工过程和成桥后该桥各控制截面实测应力和理论应力基本一致，均有与理论计算结果相符合的应力储备，满足设计要求，达到了监控目的。

The measured stress and numerical simulation indicated that the whole tensile crack and the arc tensile crack were correspondent to the distribution of maximum tensile stress, the magnitude of which increased due to transition effect.

应力测试与数值模拟证明弧形拉裂和整体贯穿拉裂同最大拉应力分布相对应，并且受迁移影响边坡坡顶最大拉应力值增大。
