“…Against the backdrop of an aging infrastructure, the notable rise in trafc volume and load has resulted in cracking, severe compression deformation, and even disengagement of the rubber bearings in numerous bridges [1]. Tese bearing diseases severely restricted the free deformation of the structure, causing the structure to generate additional internal forces on the bearing capacity of the bridge [2]. Te standard method of bearing replacement is to jack up the main girder, transfer the load from the bearing to a jack, subsequently replace the bearing, and ultimately transfer the load from the jack back to the bearing by dropping the girder [3].…”

“…To clarify the effect of varying the parameters of BSs on the dynamic response of vehicle-bridge coupling vibration, many researchers have conducted active experiments [19][20][21][22][23][24][25][26][27]. 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.…”
