Federal Highway AdministrationButh, Eugene; Hirsch, Teddy James; Henderson, MattUnited States. Federal Highway AdministrationFederal Highway AdministrationIn some connections of W-beam and thrie-team guardrail elements, it is necessary to 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.79
