2021, 36(10): 7-15. doi: 10.13206/j.gjgS21091001
Abstract:
For two type of distortion-induced fatigue details at web gaps(vertical stiffener web gap and horizontal gusset plate web gap) in the steel plate girder bridges, finite element models of the straight, skewed and curved three-span continuous steel pla...
Research on Extremely Low-Cycle Fatigue Crack Initiation and Propagation of Thick-Walled Steel Box-Section Bridge Piers
Ting Zhu, Shengbin Gao
2021, 36(10): 16-24. doi: 10.13206/j.gjgs20061203
Abstract:
In order to investigate the Extremely Low-Cycle Fatigue(ELCF) crack initiation life and crack propagation process of thick-walled steel box-section bridge piers, a series of thick-walled steel box-section piers subjected to a constant vertical load a...
Study on Effect of UIT on Welded Residual Stress of Innovative Doubly-Welded Rib-to-Deck Joint in Orthotropic Steel Decks
Hongsheng Liu, Yongchuan Luo, Shaohui Han, Qinghua Zhang
2021, 36(10): 25-33. doi: 10.13206/j.gjgs20092301
Abstract:
Compared with traditional singly-welded rib-to-deck joint(SRJ), there exists a greater number of welds and more complicated welded residual stress(WRS) distribution in innovative doubly-welded rib-to-deck joint(DRJ), and it is of great significance i...
Research on the Fatigue Performance of Rib-to-Deck Welded Joints of Wujiagang Yangtze River Bridge
Kening Hu, Houdeng Zhang, Fan Wu, Zhixing Zhou
2021, 36(10): 34-41. doi: 10.13206/j.gjgs20092801
Abstract:
The fatigue cracks in the rib-to-deck welded joints are typical fatigue diseases in orthotropic steel deck. The fatigue crack penetrating through the deck will cause secondary diseases such as pavement damage, water seepage and corrosion, which will ...
