“…When the suspender is cut for the first time, its area reduces delta ∆ 1 , during the descent of the bridge deck system, the pocket hanging system takes part in the force of the system together, and the internal force of the old suspender and the pocket hanging system is rebalanced. Equivalent tensile stiffness 1 can be obtained according to (4), then one has…”

“…However, both the half-through and through arch bridge need to transfer the load through the suspenders. Within components of a suspender arch bridge, suspenders transmit wind or live loads on the deck to the main rib, which are then transmitted to the earth [4]. suspender safety is directly related to the safety of the whole bridge [5][6][7].…”

“…Through field testing and numerical simulation, Roeder et al [28] pointed out that the bearing force of a BS near the beam end of a steel box girder was obviously affected by the vehicle-induced impact effect, and that BSs near the beam end were susceptible to fatigue failure under vehicle impact loads. Wang et al [29] investigated the fatigue cracking mechanism of the BS of a half-through steel arch bridge through field testing and numerical analysis, and indicated that the vehicle-induced longitudinal displacement of the main girder mainly resulted in the fatigue cracking of the BS. Zhu et al [30] conducted field testing of the dynamic response of vehicle-bridge coupling for a concrete girder bridge, and pointed out that the damage of BS was a susceptible disease of simply supported girder bridges, and the bearing damage may amplify the vehicle-induced dynamic response of the bridge and BS.…”

To study how varying the parameters of expansion joints and bearing supports (E-B parameters) affects the dynamic response of a coupled vehicle–bridge system for curved girder bridges, a dynamic response analysis method for the coupled vehicle–joint (bearing)–bridge system, which takes into account centrifugal forces, was proposed and verified. Subsequently, taking a continuous curved box girder bridge as the prototype, the influence of the E-B parameters on the vehicle-induced dynamic response of the curved girder bridge was explored. The results showed that the dynamic amplification factor (DAF) of the middle beam of the expansion joint (DAF-EJ) and the main girder of the curved bridge (DAF-MG) were both significantly influenced by the E-B parameters. When there were height differences between the middle beam and side beam in the EJ, the DAF-EJ obviously varied, and the DAF-MG increased. When the EJ was damaged, the impact effect of the vehicle on the bearing support increased. The DAF-EJ and DAF-MG both increased with the decrease of the vertical support stiffness of the bearing support. The DAF-EJ was greatly affected by the single-support void at the near-slit end of the lane. The DAF-MGs at the beam end, the 1/4 point and 1/2 point of the first span, and the 1/2 point of the second span, were significantly affected by the single-support void near the measuring point. Compared with the single-support void, the DAF-EJ and DAF-MG more significantly increased under the double-support void. Variation in the height difference of the EJ had a more significant effect on the DAF-EJ and DAF-MG at the beam end, while a vertical stiffness reduction in the bearing support had a more significant effect on the DAF-MG.

“…Therefore, the expansion joint is prone to a variety of diseases during its service life, such as supporting girder failure, transverse girder fracture, anchor zone damage and so on. Moreover, these diseases of expansion joint will lead to a significant change of the vehicle‐induced dynamic response of bridge components 3–7 . Further, the above diseases of expansion joint may cause the accompanying diseases of main components of bridge, such as bearing failure, bridge deck pavement damage, main girder cracking and suspender fracture.…”

Parameters' change of expansion joints has significant impact on the vehicleinduced dynamic response of bridges. However, it is uneconomical to conduct health monitoring to evaluate the technical condition of expansion joint. To indirectly evaluate the service performance of expansion joint and clarify the impacts from variations of the expansion joint parameters on the vehiclebridge coupling vibration response, an analysis method of vehicle-expansion joint-bridge coupling vibration (VBCV-J) was established and verified. Then, taking a long-span concrete filled steel tubular arch bridge as the prototype, the vehicle-bridge coupling vibration response were studied using the VBCV-J model while considering the cases of design parameters and variation parameters of the expansion joint. The results show that, for the design parameters, the dynamic amplification factor (DAF) of the expansion joint and the beamend measuring points of the main girder are significant. The DAFs of the short suspenders near the expansion joint is also greater than that of suspenders in the 1/4 span and 1/2 span. For the variable parameters, the variation in the height difference between the middle transverse girder and the side transverse girder will lead to a significant increase in the vehicle-induced impact on the end of the main girder, the short suspender, and in the reaction force of the supports. The decrease of the support stiffness will also make the DAFs of the above components exceed the design value. The variation of the vehicleinduced dynamic response of main beam-end and suspenders can indirectly reflect the service performance of expansion joint. K E Y W O R D S disease impact, dynamic amplification factor, expansion joint, indirect health monitoring, vehicle-bridge coupling vibration Jianling Hou and Weibing Xu contribute equally to the article.
