Abstract
The Midwest Roadside Safety Facility, in cooperation with the Federal Highway Administration and U.S. Department of Agriculture Forest Service. Forest Products Laboratory. developed and tested two bridge railings for use on longitudinal timber bridge decks: (a) a steel railing system (TBC-8000) and (b) a glulam timber railing system (GC-8000). The test for the TBC-8000 was conducted according to Performance Level 2 as specified in the AASHTO Guide Specifications for Bridge Railings (1989). The tests for the GC-8000 were conducted according to Test Level 4 as specified in NCHRP Report 350. The safety performance of each of the bridge railings was acceptable according to each applicable crash test criterion. Both railings provide aesthetically pleasing and economical alternatives for use on higher-service-level timber bridges.
