2.24 A rubber bearing pad under the steel girder above is used to produce a relatively uniform bearing stress on the concrete below. The literature from the pad manufacturer suggests that strain in the particular bearing pad should not exceed 12%. Due to the dead loading of the structure's weight, the pad is already strained by 3%. Say the live loads could produce an additional 0.25 in. of vertical motion of the girder, which must be tolerated. Determine the acceptable range of pad thicknesses that keeps strains below the maximum allowable strain.
