Performance of a Thrie-Beam Steel-Post Bridge-Rail System

J. E. Bryden / R. G. Phillips

Twelve full-scale crash tests were performed to evaluate the performance of a thrie-beam bridge-rail system. The system was tested both with and without a 6-in. curb, with rail height of 33 in.--measured from the deck--for both designs. Also tested were transitions from W-beam guiderail on S3x5.7 posts to thrie-beam guiderail on W6x9 posts, and from the thrie-beam guiderail to the bridge rail. This railing can be used on either new or existing structures, with or without curbs, and requires no attachment to existing railing or structural members. It offers a relatively low-cost railing and because it relies primarily on components common to other barriers, it minimizes maintenance inventory requirements.
