Improving Transportation Infrastructure Resilience against Hurricanes, other Natural Disasters, and Weathering: Part I - Analysis of failure of transportation signs due to Hurricane Maria
| 项目名称： | Improving Transportation Infrastructure Resilience against Hurricanes, other Natural Disasters, and Weathering: Part I - Analysis of failure of transportation signs due to Hurricane Maria |
| 摘要： | The primary goal of this proposal is to analyze the failure of different types of transportation signs due to Hurricane Maria. The specific objectives of the project are: (a) determine the causes of the failure, (b) suggest improvements to the design and construction to avoid or reduce the risk of damages in future hurricane situations, and (c) calculate the wind loads that produced the damage in order to better establish the design wind speed in Puerto Rico (PR) new building codes and Department of Transportation (DOT) specifications. The intended outcome of the project is to improve the design and construction of highway and roadway signs. Also, the findings could motivate ASCE, the Institute of Civil Engineers of the College of Engineers and Land Surveyors of Puerto Rico, and Puerto Rico Building Code Officials (PRBCO) to change the design wind speed established for Puerto Rico, which in turn will affect the design of transportation infrastructure. PRDOT may also decide to adopt the assessed wind speeds for their design, aside of any ASCE or PRBCO decision. |
