Book Description
This report documents the results of a full-scale crash test with a minicompact car on the aluminum tru-beam bridge railing. The purpose of the test was to determine whether geometrics of the railing system were adequate to prevent snagging of the vehicle. This railing design had been developed from the Indiana 5A railing design after strength problems had been discovered in full-scale crash tests of the design in a previous study. The Indiana 5A railing design was modified by replacing the lower rail element with a tru-beam rail. The performance of this aluminum tru-beam railing system was acceptable when subjected to a test with a 4,500 lb (2,041 kg) vehicle. Subsequently, in this study, the tru-beam design was subjected to a test with a 2,150 lb (975 kg) Honda to see if the new design would preclude snagging of the small vehicle. Performance of the railing was acceptable by criteria in NCHRP 230.

Book Description
"This project evaluated bridge railings. State bridge rail designs submitted to the Federal Highway Administration (FHWA) were rated and the best of each type were selected for crash test evaluation. When necessary, the designs were improved and retested. Most of the crash tests were conducted with 4500-lb (2025-kg) cars at 60 mph (95 km/h) and a 25-degree angle and 1800-lb (800-kg) cars at 60 mph (95 km/h) and a 20-degree angle. Performance standards are proposed in 1986 are presented, along with bridge railing geometric design considerations to minimize vehicle snagging. Design drawings of the successfully tested bridge rails are included"--Technical report documentation page

Book Description
This study consisted of strength analyses of five in-service bridge railing systems, thirty full-scale vehicle crash tests on those railing systems and on a load measuring wall, the development of recommended design guidelines and development of recommended performance standards. The spectrum of vehicles addressed ranged from an 1,800 lb Honda sedan to a 32,000 lb intercity bus. Some of the in-service railings were found to have poor performance in full-scale crash tests.

Book Description
A total of seven vehicle crash tests were performed, three involving a Type 115 bridge rail and four involving a thrie beam bridge rail. Additional static testing was done on five steel bridge rail posts with different types of post stiffeners. The Type 115 bridge rail consisted of two tube steel rails (4x4x0.25 in.) supported off the edge of deck by steel wide flange posts at 8 ft 0 in. spacing. The thrie beam bridge rail consisted of 10 ga. thrie beam panels blocked out and supported on the edge of deck by steel wide flange posts at 6 ft 3 in. spacing. The typical heights for the Type 115 and the thrie beam bridge rails were 30 and 32 in., respectively. There were two impact tests on the Type 115 bridge rail, one on the Type 115 bridge rail transition, two on the thrie beam bridge rail, and two on the thrie beam bridge rail transition.
