CAREER: An Innovative Performance-Based Simulation Framework for High-Rise Buildings against Wind Hazards

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(CAREAR)项目的研究目标是开发一种分析受风灾影响的高层建筑的风荷载和结构响应不确定性的方法。这项研究将有助于通过分析和数值模拟相结合的方法来量化这种不确定性，并将通过风洞实验研究来验证这一点。人们的注意力将集中在天气风和飓风造成的负荷上。交付成果将包括实施一套用于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)建筑物外墙的损坏，3)其他非结构构件的损坏，4)严重风暴过后基本设施的即时占用标准。这项研究活动的结果将有助于将受风灾影响的高层建筑的经济损失降至最低。研究结果还将为结构设计简化设计规则的推导提供参考。综合教育和外展活动将包括：对研究生和本科生进行直接培训，为研究生和本科生进行系级和学院范围的演示，创建一个提高对风灾的认识的专家系统，为执业工程师举办短期课程，通过与风能工程网络基础设施网络的合作共享技术和数据。

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
