摘要
由于重复荷载以及车辆等动荷载的作用,组合梁的疲劳问题日益突出,目前组合梁在桥梁工程上应用时间较短,疲劳问题尚未显露,因此需要对组合梁疲劳进行更深入的研究。文章对栓钉疲劳性能影响因素、栓钉疲劳寿命计算模型以及近几年来国内外有关组合梁的发展状况进行分类总结,为疲劳荷载作用下钢-混凝土组合梁设计提供参考建议。
Due to the impact of repeated load and dynamic load such as vehicles, the fatigue problem of composite beam has become increasingly prominent, Currently the application of composite beam in bridge engineering has not been a long time yet,its fatigue problem has not been revealed,thus it is required to further study the fatigue problem of composite beam.This article classified and summarized the influencing factors of studs fatigue performance, stud fatigue life calculation model, as well as the relevant domestic and foreign composite beam development situation in recent years, thereby provi- ding the reference recommendation for steel-concrete composite beam design under fatigue loads.
