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。目前的结构体系和设计策略导致高层建筑在控制风致振动方面效率低下,并且预计在地震后会遭受相当大的破坏。目前迫切需要提高高层建筑对极端风荷载和地震荷载的适应能力。本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,这些高层建筑对极端荷载的适应能力更强,本项目的短期目标是:i)对新提出的弯剪基底机制进行首次大规模实验验证,ii)使用新开发的UT-SIM建模平台开发先进的数值模型(ut-sim.ca)以提高在严重荷载条件下的全局建模能力,并更好地评估采用这些先进技术的建筑物的性能。结构系统和最佳分布阻尼系统,iii)在加拿大对多个高层建筑进行全面监测,以及iv)详细阐述一种基于风性能的综合设计方法,该方法与当前基于性能的地震设计方法相一致并集成。这项研究不仅将使加拿大工程师能够使用这些新系统和先进性能-该项目将采用基于设计的方法,以提高其在加拿大设计中的弹性,同时也将使加拿大的顾问和承包商在世界舞台上竞争一些世界最高建筑的设计和建造方面具有优势。
