To obtain force data for spherical bearings and facilitate the monitoring and evaluation of the operational status of bridge structures, a new type of force-measuring spherical bearing is studied. This design incorporates fiber optic grating sensing technology to detect the vertical load-bearing capacity of the bearings. Through experimental testing, it has been confirmed that this new type of force-measuring spherical bearing can conveniently and accurately collect the actual force distribution in engineering structures. It can provide effective scientific evidence for assessing the health condition of bridge structures.
