CAREER: A Design/Test Environment with Integrated Experimental and Computational Simulation of Unsteady Wind Loads for Mitigation of Wind-Related Natural Hazards

该项目的研究和教育活动旨在减轻与风有关的自然灾害--美国面临的代价最高的自然灾害。第一个目标是建立一个设计和测试环境（DTE），在这个环境中，不同的参与者可以学习，设计和测试抗风设计的新概念。其次，将开发基于离散涡方法（DVM）的计算模拟工具。第三，实验和计算工具将以这样一种方式整合，即随着设计的测试，模型和工具将不断得到验证和改进。从研究的角度来看，DTE将促进研究人员，学生和行业之间的互动，以构思抗风设计的新概念。这些概念将使用实验和计算工具进行测试。因此，进行研究以寻求改进的空气动力学设计和改进计算技术。作为一种教育工具，DTE将容纳来自各种背景的研究和设计参与者，并在适当的水平上工作。DTE的所有活动--提交待测设计和报告测试结果--都可以通过Internet访问。该项目的智力价值来自于模拟的综合实验和计算性质以及离散涡方法的基础。该项目更广泛的影响包括新的抗风设计开发，新的设计计算工具，任何设计结构的人都可以访问的气动载荷数据库，以及促进来自广泛背景的人参与的框架。

Research and education activities in this project pursue the mitigation of wind-related natural hazards-the most costly natural hazards faced by the United States. The first objective is to establish a design and testing environment (DTE) in which a diverse collection of participants can learn, design, and test new concepts in wind-resistant design. Second, computational simulation tools will be developed based on discrete vortex methods (DVM). Third, experimental and computational tools will be integrated in such a way that as designs are tested, the models and tools are continuously being validated and improved. From a research standpoint, the DTE will facilitate interaction among researchers, students, and industry for conceiving novel concepts in wind-resistant design. These concepts will be tested using both experimental and computational tools. Research is therefore conducted to search for improved aerodynamic designs and to improve computational techniques. As an educational tool, the DTE will accommodate research and design participants from a wide range of backgrounds working at an appropriate level. All the activity of the DTE-submission of designs to be tested and reporting test results-will be accessible via the Internet.The project's intellectual merit derives from the integrated experimental and computational nature of the simulations and the foundation of discrete vortex methods. The project's broader impacts include new wind resistant design development, new computational tools for design, a database of aerodynamic loads accessible to anyone designing a structure, and a framework that fosters participation by people from a broad range of backgrounds.
