| 摘 要： | 采用疲劳列车，将各种疲劳列车模拟通过两座铁路大跨度连续梁桥，以获取连续梁控制截面的疲劳荷载效应谱；将疲劳荷载效应与标准荷载最大效应建立关系，便可得到连续梁控制截面的标准荷载效应比频谱。利用标准荷载效应比频谱，可计算出钢筋的等效等幅应力换算系数。

| Abstract: | In the paper, fatigue trains are applied to check the fatigue behavior of concrete continuous beams. According to fatigue trains, two railway long-span PC or PPC continuous beams are loaded through computer simulation, the transportation stresses of controlling sections of continuous beams are acquired and compared with the maximum fatigue stress range produced by Chinese railway standard traffic loading. The effect ratio spectrums of standard load and the equivalent constant amplitude repeated stress of controlling sections are calculated. |
