PERFORMANCE LEVEL 1 BRIDGE RAILINGS

Twenty-three states, FHWA, and the District of Columbia sponsored the project Testing of New Bridge Rail and Transition Designs that was completed in September 1993. Bridge railing for Performance Levels 1, 2, and 3, as specified in the 1989 American Association of State Highway and Transportation Officials "Guide Specifications for Bridge Railings", were tested under the contract. This paper discusses the design and performance of the two bridge railings tested at Performance Level 1. The Oregon side-mounted railing has been used on small bridges on low-volume rural roads and is typically mounted on prestressed deck planks. The W6 X 15 posts are mounted on the side face of exterior planks, and a single thickness of 10-gauge thrie beam is mounted to the posts without blockouts. Height to the top of the rail element is 690 mm (27 in.). The BR27D railing design consists of a concrete parapet with a metal beam-and-post railing mounted on top of the parapet. For testing, it was mounted both on top of a sidewalk and flush on the deck.
