Wind and Earthquake Resilience of High-Rise Buildings

点击翻译按钮获取中文摘要

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.
