TxDOT T1W Bridge Rail

Report Number(s): 0-6946-R2

Description: The TxDOT T1W test installation consisted of two rectangular tubular steel rail elements attached to fabricated steel posts mounted on a concrete curb that was cast on an 8-inch reinforced cantilevered concrete deck. The curb was 9 inches tall and 14 inches wide, and had embedded anchor bolts for attachment of the steel posts. The posts were spaced on 9 ft centers. The total height of the rail was 32 inches above the deck. Two joints extended through the curb and one of the joints continued through the cantilever deck. The joint in the parapet was for geometric evaluation of the passenger car during Test 3-10 (the 1100C test location). The other joints that extended through both the parapet and deck provided evaluation of both rail geometry and structural adequacy during Test 3-11.
