| 摘要： | This study focuses on the development of a cost-effective, timber guardrail that utilizes low-grade New England hardwoods such as red maple and beech. In order to be accepted for highway applications, the rail must be capable of passing the NCHRF Test Level 3 (TL-3) crash test (NCHRP 1993), and be easily installed using a standard post spacing of 1.83-m. Developing a rail to meet these requirements required significant effort on several fronts, including analyzing the response of the rail under vehicular impact, designing the rail section, fabricating rail specimens, evaluating the durability of the guardrail, developing a rail-to-rail field splice connection, and experimentally evaluating the structural performance of the guardrail. The remainder of this Section provides an introduction to timber guardrail systems and overview of this report. |
