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。该教师早期职业发展（Career）项目的研究目标是开发一种方法，用于分析受风灾影响的高层建筑的风荷载和结构响应不确定性。本研究将通过分析和数值模拟相结合的方法对这些不确定性进行量化，并将通过风洞实验研究进行验证。注意将集中在由天气风和飓风引起的荷载。交付成果将包括一套用于损伤量化的数值和分析计算机方法的实施。将考虑以下问题：1)居住者的不适程度，2)建筑物正面的损坏，3)其他非结构部件的损坏，4)在严重风暴之后基本设施的立即使用标准。经济影响的分析，例如与维护维修和停机损失相关的分析，将被处理。研究结果将有助于最大限度地减少受风害影响的高层建筑的经济损失。研究结果也将为结构设计简化设计规则的推导提供参考。综合教育和推广活动将包括：直接培训研究生和本科生，为研究生和本科生提供系级和学院范围的示范，建立一个专家系统，提高对风力危害的认识，为实习工程师提供短期课程，通过与风力工程网络基础设施网络合作共享技术和数据

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
