| 摘要： | This final project report presents the design details and full-scale test results of the phase two low profile barrier. The phase one design was re-worked in order to permit horizontal and vertically curved layouts and improve in-field ease of installation. The iterative design process was completed based on computer simulations of vehicle impact. The final product is a barrier system consisting of 12-foot segments with an 18-inch he shear and moment-transfer while permitting flexibility in layout curvatures. No anchorage to the ground is required. Fifteen specimens were fabricated, installed as a system, and crash tested to the level 2 specifications in NCHRP Report-350. The tests were successful and the barrier system was certified. Segments are connected together with a unique system that allows both |
