Testing of New Bridge Rail and Transition Designs. Volume 14: Appendix M. AxialTensile Strength of Thrie and W-Beam Terminal Connectors

摘要

In some connections of w-beam and thrie-beam guardrail elements, it is necessaryto bolt together three thicknesses of rail element. Such a connection can not be assembled without enlarging the standard round connection bolt holes. One solution to this problem is to use elongated holes with the long axis of the hole at an angle to the longitudinal axis of the rail element. A number of static load tests were performed to investigate the strength of terminal connectors with slanted elongated splice holes.
