437 CHAPTER 17 – CONCLUSIONS One of the oft-touted advantages of strong-post w-beam guardrails is that they can retain some effectiveness even after having been struck and damaged. It is not always easy to discern, however, when the extent of damage warrants repair and when the damaged barrier is still largely functional.

438 element analysis was then used to investigate the effects of damage modes on overall system performance. For example, pendulum tests were used to quantify reduction in post strength as a function of deterioration (e.g., rot or insect damage)
