The selection of bearings for a structure depends on consideration of a number of factors by designers. The success or failure of the entire structure may depend on the performance of these devices. There are a number of bearing types available on the market. In some situations, only one type of bearing may be appropriate for the particular type of structure, while in other situations the designer has to select from the variety of bearings available. The precise function of bearings will obviously vary between structures and even from one end to another end within a given structure. The bearing selection criteria described in this paper is dedicated to assisting the designer when selecting an appropriate and efficient bearing, to perform all structural functions with the least maintenance during the life of the bridge. Experience has shown that with a careful study of the functions, limitations, and initial and maintenance costs of the bearings, the designer can achieve the most desirable bearing.
