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

钢板剪力墙是一种抗侧力的结构体系，主要基于对其在严重地震荷载下预期性能的研究而发展到高级阶段。虽然该系统非常适合高地震区域，但其他重要的潜在应用在很大程度上被忽视，例如用于保护结构，工业结构和结构中，其中固有的系统冗余可以有效地用于减轻潜在的连续倒塌情况。整体研究计划的主要目标是探索钢板剪力墙在加拿大大部分地区的未开发应用，其中抗震设计考虑因素不太重要。在这个过程中的第一步是制定合理的放松钢板剪力墙，已被视为必要的代码和标准，以实现非常高的延性和循环鲁棒性的高成本的详细要求的手段。作为实现总体计划目标的一个重大进步，在本研究项目期间，将制定适用于低、中地震区的不太严格的设计要求，并在实验室中通过相应设计的大规模物理试验验证其有效性。本研究项目的成果对加拿大建筑业、建筑设计专业人员和建筑业主的主要好处是，可以经济地设计钢板剪力墙系统，以利用其在低和中等地震区域的固有抗震性能，而无需昂贵和不必要的详细规定。

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.
