| 摘要： | A common issue during phased highway construction projects is the need to temporarily relocate large guide signs on the roadside or install new guide signs for temporary use. The conventional concrete foundations used for these signs are costly and time consuming to install and remove after construction is completed. Direct embed wood and steel post support systems for temporary large guide signs were developed and successfully crash tested in accordance with MASH guidelines. The designs considered wind loads, foundation requirements, and impact performance. The direct embedded support posts eliminate the need for reinforced concrete foundations. The results of the research can be used to establish acceptance of other less critical design configurations for other sizes of temporary guide signs. Variations include different post size, grade, and spacing. |
