Abstract. Chongqi bridge is the longest-span continuous steel box girder bridge with an orthotropic steel deck in China. Due to the small thickness of both the deck plate and rib wall, the out-of-plane bending moments result in high local flexural stresses causing fatigue cracks to develop at the rib-to-deck joints. Aiming at the fatigue problem of this joint in the orthotropic steel bridge deck plate, the stress amplitude is calculated by FEM and the fatigue properties of rib-to-deck joints was analyzed according to the Eurocode specification under the condition of the single path loading. The results show that rib-to-deck joints have adequate fatigue strength and no fatigue cracks would occur at the location under the given fatigue loads. General situation of the Chongqi Bridge [1]The main bridge of Chongqi bridge is a 6-span single box single room variable cross-section continuous girder bridge of 102+4×185+102(m).The height of the girder is 4.8m in the mid-span and 9m in the intermediate support, while the depth-span ratio is 1/38.54 and 1/20.55, respectively. Fig.1(a) and (b) show the cross-section. Orthotropic deck is adopted in Chongqi bridge because of its favorable characteristics such as high load-carrying capacity, light weight, and short installation time. The structural parameters of the Chongqi bridge main girder are briefly summarized as follows. The thickness of the deck plate is 18 mm. The cross section of the longitudinal rib is 285 mm (top width) · 280 mm (height), and the thickness of the rib wall is 8 mm. The spacing of the main girder web plates is 7.5m and the thickness of the main girder web plates is 16mm. The spacing of the diaphragms is 5.6m, the spacing of transverse stiffener between the diaphragms is 2.8m. The thickness of the diaphragm plate is 12mm and the height of the diaphragm is 1

“…A mayor concern about the railway transportation system is whether these asbuilt high-speed railway bridges are robust enough to carry the ever-increasing transportation. Considerable railway bridges were built in steel for lighter weight and easier construction [3,4]. However, steel material and structure are vulnerable to suffering corrosion and fatigue issues especially in welded positions.…”

“…As the experience accumulate, the details of the structure become more reasonable than before and the manufacture process of orthotropic steel deck has been improved. Such as the trend to increase the thickness of the deck plate from 12mm(Hu Men bridge, Jiang Yin bridge, Hai Cang bridge) to 14mm (Run Yang bridge, Xi Houmen bridge), then the thickness increase to 16mm (Ping Sheng bridge, Jia shao bridge), and even increase to 18mm (Tao Huayu Yellow River bridge, Gang Zhu Ao bridge) [1][2][3][4]. In Severn Bridge the transverse crossbeam cut-through the longitudinal ribs and there were several cracks generated in crossbeam to longitudinal rib welds.…”

Abstract. Four kinds of fatigue cracks are found in a suspension bridge with orthotropic steel deck. Finite element analysis was conducted to investigate the reason of fatigue cracks originated from the cope hole in the transverse crossbeams. The stresses surround the cope holes in the crossbeam are calculated under vehicle loads which are imposed on scheduled positions on the bridge deck. Then the relationship between the peak stresses surround cope hole and the loading position is acquired. There are 2 areas have the effects of stress concentration surround a cope hole, which are named area-A and area-B. The calculation results indicate that the peak stress in area-A is greater than the allowed fatigue stress-range under 2 million cyclic loads, and the actual position of fatigue crack detected in the bridge is coincide with the position of area-A.
