STANDARD SAFETY BARRIERS FOR ENGINEERING STRUCTURES

BARRIERES NORMALES DE SECURITE SUR OUVRAGE D'ART

This article reviews the research programme on safety barriers for engineering structures, carried out by the SETRA since 1967. The study described is based on 17 full-scale dynamic tests (5 with a lightweight vehicle, 12 with a 12-tonne heavy vehicle of the coach type) and 15 static impacts tests. All tests were conducted at the ONSER laboratory at Lyon-Bron. The test procedures are described and the test results are grouped for each element: supports, rails, anchorage bolts, anchorage, bearing structures. Emphasis is placed on the barrier-rail connection and the problems linked with deck structure. This study led to the development of a metal barrier capable of redirecting a 12-tonne coach colliding with it at a speed of 70 km/h at an impact angle of 20 degrees. The cost-effectiveness of the study is demonstrated. /TRRL/ /TRRL/
