Standard Practice for Design of Journal Bearing Supports to be Used in Fiber Reinforced Concrete Beam TestsMore info
1.1 This practice prescribes the design of journal-bearing type rollers to support each end of fiber-reinforced concrete beams tested using Test Method C1399/C1399M or Test Method C1609/C1609M. The roller design is intended to provide a consistent and relatively low value of effective coefficient of friction at the beam supports. The bearing design incorporates metal-on-metal sliding surfaces lubricated with grease.
Note 1: During the progress of a test, a crack or cracks open on the underside of the beam between the loaded third points causing the underside of each portion of the beam to move away from the center. The design is intended to provide for unlimited rotation of the roller at the point of contact with the test beam in response to this motion.
