DEVELOPMENT OF RETROFIT RAILINGS FOR THROUGH TRUSS BRIDGES
The design and development of bridge railing systems for through truss structures are described in this paper. The unique design of these structures makes rigid railings mandatory to exclude the errant vehicles from the truss members located behind the railing. The two systems were designed to meet different performance conditions. The high-performance system contained and redirected a 20,000-lb (9000-kg) bus impacting at 55 mph (90 km/h) and a 15-degree angle. The low-service-level system contained and redirected a 4,500-lb (2000-kg) car impacting at 60 mph (95 km/h) and a 15-degree angle. In addition, 2,250-lb (1000-kg) and 1,800-lb (800-kg) cars were used to evaluate the systems, including the bridge approach railing, for the high-performance system. The two systems meet the design criteria and are recommended for immediate implementation.
