| 摘要： | Under a previous study, Texas Transportation Institute (TTI) and TX DOT worked cooperatively to conceptualize and develop two aesthetically pleasing and crashworthy rail designs. The rails were designated the T77 and the F411. Researchers performed and evaluated full-scale crash tests on the new rails in accordance with National Cooperative Highway Research Program (NCHRP) Report 350 test 3-11. The TX DOT F411 bridge rail performed acceptably according to the evaluation criteria of NCHRP Report 350. However, the T77 design failed to perform acceptably with the pickup truck. The objective of this project was to modify the TX DOT T77 bridge rail to perform as an aesthetically pleasing and crashworthy bridge rail. TT1 and TX DOT worked cooperatively to modify the design to make the rail perform satisfactorily. Researchers performed full-scale crash tests in accordance with NCHRP Report 350. The T77 bridge rail was modified so it would perform in accordance with the evaluation criteria for NCHRP Report 350 test 3-11. |
