Galvanizing Effect on the Fatigue Performance of Sign and Signal Socket Connection Details
| 项目名称： | Galvanizing Effect on the Fatigue Performance of Sign and Signal Socket Connection Details |
| 摘要： | In 2007 a failed Virginia cantilevered sign pole was forensically investigated at Turner-Fairbank Highway Research Center. The investigation yielded inconclusive results, but evidence of zinc on the fracture surface raised a suspicion that a crack may have been preexisting from fabrication. In discussions with industry there appeared to be a growing problem in the US with hot-cracking or liquid metal embrittlement of these details. This project was a first step to addressing the concern, that being to define the reduction in fatigue strength due to galvanizing of socket connection details. |
