Economical steel plate shear walls for Canada's low moderate seismic regions

点击翻译按钮获取中文摘要

Steel plate shear walls are a lateral load resisting structural system that has been developed to an advanced stage primarily based on research that focuses on its expected performance under severe earthquake loading. Although the system is undeniably well-suited for high seismic regions, other important potential applications have largely been neglected, such as use in protective structures, industrial structures, and structures where the inherent system redundancy can be used effectively to mitigate potential progressive collapse scenarios. The primary objective of the overall research program is to explore untapped applications for steel plate shear walls in the majority of the regions of Canada, where seismic design considerations are less critical. The initial step in this process is to develop means of rationally relaxing the costly detailing requirements for steel plate shear walls that have been deemed necessary by codes and standards to achieve very high levels of ductility and cyclic robustness. As a major advancement toward achieving the overall program objective, less-stringent design requirements will be developed during this research project for application in low and moderate seismic regions, and their efficacy will be verified in the laboratory by a large-scale physical test designed accordingly. The major benefit of the outcome of this research project to the Canadian construction industry, building design professionals, and building owners will be a well-defined means of designing steel plate shear wall systems economically to take advantage of their inherent seismic performance in low and moderate seismic regions, without costly and unnecessary detailing stipulations.
