Flexural-Shear Base Mechanisms and Distributed Damping Systems for Combined Wind Efficiency and Seismic Resilience of High-Rise Buildings

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. This research is focused on developing a new approach for the design of high-rise buildings where all critical elements are modular engineered systems that provide effective damping for both wind and earthquake loading and allow for the rapid inspection and repair of the structure immediately after an earthquake. The research will define these innovative structural systems for tall buildings, enhance the understanding of the theoretical dynamics of self-centering flexural-shear base systems with coupling damping elements, develop new simulation methodologies for predicting their dynamic response, and will result in a comprehensive integrated wind and earthquake performance based design methodology. This research will not only allow Canadian engineers to use these new systems in their 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.
