CSU/TTU Cooperative Wind Engineering Program

9409869 9411147梅塔·梅罗尼合作风能工程项目(CWEP)进入了由科罗拉多州立大学和德克萨斯理工大学的研究人员组成的跨学科团队共同开展的第二个五年期研究活动周期。合作研究计划将继续专注于三个主要领域：风荷载、风工程气象学和建筑物周围的风流。在三个主要领域进行的研究将结合全尺度现场物理模拟和风洞物理模拟，每个领域都将整合到另外两个领域。在风荷载方面，将继续研究数据采集和分析、渗透面压力、建筑和机械特征的影响、风荷载的空间结构和时间结构，以及对低高度建筑物风荷载可靠性分析的研究。在风工程气象学领域，仪器的改进和对风流记录特别是NEXRAD数据的改进分析，以及边界层风洞中的风暴模拟是需要研究的一些课题。在建筑物周围的风流领域，建筑物表面附近分离区的识别、雷诺数的影响、使用激光薄片可视化来检查风流的时变性、建筑物形状、屋顶线和其他特征的影响、遮挡和地形效应以及数值模拟都是需要研究的一些课题。在这三个主要领域所做工作的成果将在整个方案期间综合起来。根据这项计划的结果，处于危险中的人口的安全将得到改善，私营部门，如建筑和保险行业，将受益，因为新建和翻新的建筑和结构的脆弱性将降低；联邦、州和地方管理人员将继续受益于新的和改进的缓解措施的开发；研究界也将从计划期间开发的数据、仪器和方法中获得知识。***

9409869 9411147 Mehta Meroney The Cooperative Wind Engineering Program (CWEP) enters the second five-year cycle of research activities undertaken by an interdisciplinary team of researchers from Colorado State and Texas Tech Universities working jointly. The cooperative research program will continue focusing on three main areas: wind load, wind engineering meteorology and wind flow around buildings. The combination of full scale field and wind-tunnel physical modeling will be merged in studies conducted in the three main areas and each will be integrated into the other two. On Wind loads, studies will continue in topics such as data acquisition and analysis, pressures on permeable surfaces, the influence of architectural and mechanical features, the spatial and temporal structural of wind loads, and on wind loading reliability analysis of low-raise buildings. In the area of wind engineering meteorology, instrumentation refinements and improved analysis of wind flow records especially of NEXRAD data, and the simulation of wind storms in the boundary layer wind tunnel are some of the topics to be studied. In the area of wind flow around buildings, the identification of the separation region near the surface of structures, the effect of the Reynolds number, the use of laser-sheet visualization to examine the time-dependent nature of the wind flow, the effect of building shape, roof line and other features, shelter and topographic effects, and numerical modeling are some of the topics to be studied. The results from the work done in these three main areas will be integrated throughout the duration of the program. Based on the results from this program the safety of populations at risk will improve and the private sector, such as the construction and insurance industries, will benefit because the vulnerability of new and retrofitted buildings and structures will decrease; the Federal, State and local administrators will continue to benefit because o f the development of new and improved mitigation measures; and the research community also will gain knowledge from the data, instrumentation and methods developed during the program. ***
