This award is funded under the American recovery and Reinvestment Act of 2009 (Public Law 111-5)The research objective of this Faculty Early Career Development (CAREER) project is the development of a methodology for the analysis of wind loading and structural response uncertainty for tall buildings affected by wind hazards. This study will contribute to the quantification of such uncertainties through a combination of analytical and numerical simulation methods, which will be validated through an experimental study in wind tunnel. Attention will be focused on the loading induced by synoptic and hurricane winds. The deliverables will include the implementation of a set of numerical and analytical computer methods for the quantification of the damage. The following issues will be considered: 1) discomfort levels for occupants, 2) damage to the façade of the building, 3) damage to other non-structural elements, 4) immediate occupancy criteria for essential facilities in the aftermath of a severe wind storm. The analysis of economical impacts, for example associated with maintenance repairs and downtime losses, will be addressed.The results of this research activity will contribute to the minimization of economic losses on tall buildings affected by wind hazards. The outcomes of the study will also provide indication for the derivation of simplified design rules for structural design. Integrated educational and outreach activities will include: direct training of graduate and undergraduate students, department-level and college-wide demonstrations for graduate and undergraduate students, creation of an expert system for awareness against wind hazards, short courses for practicing engineers, technology and data sharing through the collaboration with a wind engineering cyber-infrastructure network

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该学院早期职业发展（CAREER）项目的研究目标是开发一种方法，用于分析风荷载和受风危害影响的高层建筑的结构响应不确定性。本研究将有助于量化这种不确定性，通过分析和数值模拟方法相结合，这将通过风洞实验研究进行验证。注意力将集中在天气和飓风引起的负载。交付的成果将包括实施一套量化损害的数字和分析计算机方法。将考虑以下问题：1）居住者的不适程度，2）建筑物立面的损坏，3）其他非结构性构件的损坏，4）严重风暴后基本设施的立即占用标准。经济影响的分析，例如与维护维修和停机损失相关的分析，将得到解决。这项研究活动的结果将有助于减少受风灾害影响的高层建筑的经济损失。研究结果也将为结构设计的简化设计规则的推导提供指示。综合教育和推广活动将包括：直接培训研究生和本科生，为研究生和本科生举办系级和学院级示范活动，创建提高风危害意识的专家系统，为执业工程师举办短期课程，通过与风力工程网络基础设施网络合作共享技术和数据
