项目摘要

Urbanization in Canada and across the world has resulted in a dramatic increase in the demand for high-rise buildings. Current structural systems and design strategies result in high-rise buildings that are inefficient with respect to controlling wind-induced vibrations, and are expected to sustain considerable damage after an earthquake. There is a pressing need to enhance the resilience of tall buildings to both extreme wind and earthquake loading.The longer term goal of this research is to contribute to the definition and validation of a next generation of high-rise buildings that are more resilient to extreme loading, the shorter term goals of this program are to: i) carry out the first large-scale experimental validations of the newly proposed flexural-shear base mechanism, ii) develop advanced numerical models using the newly developed UT-SIM modeling platform (ut-sim.ca) to improve the global modeling capabilities under severe loading conditions and better assess the performance of buildings incorporating these advanced structural systems and optimally distributed damping systems, iii) carry out a comprehensive monitoring programme of multiple high-rise buildings in Canada, and iv) elaborate a comprehensive wind performance based design approach which that is consistent and integrated to current performance-based earthquake design methodologies.This research will not only allow Canadian engineers to use these new systems and advanced performance-based design methodologies to enhance the resilience of their in designs in Canada but will also give Canadian consultants and contractors an edge to compete on the world scene for the design and construction of some of the world's tallest buildings.

加拿大和世界各地的城市化导致对高层建筑的需求急剧增加。当前的结构系统和设计策略导致高层建筑在控制风引起的振动方面效率低下，并有望在地震后承受可观的损失。迫切需要提高高大建筑对极端风和地震的载荷的韧性。这项研究的长期目标是为下一代高层建筑的定义和验证做出贡献，这些建筑物更具有极端载荷的高度载荷，该程序的较短期限是：i）使用：i）进行：i）i）进行了新的大规模实验性验证，以下是II的固定材料，并实现了新的稳定性，并实现了新的实验性依据，该型号是符合新的固定效果。开发的UT-SIM建模平台（UT-SIM.CA），以提高在严重的负载条件下的全球建模能力，并更好地评估结合这些先进结构系统和最佳分布的建筑物的性能；加拿大工程师使用这些新的系统和高级基于绩效的设计方法来增强其在加拿大设计中的弹性，但还将使加拿大顾问和承包商具有优势，以在世界各地竞争世界上一些最高的建筑物的设计和建设。
