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

钢板剪力墙是一种抗侧向荷载的结构体系，主要是基于对其在强烈地震荷载下的预期性能的研究，已经发展到一个高级阶段。虽然该系统无可否认非常适合高震区，但其他重要的潜在应用在很大程度上被忽视了，例如在防护结构、工业结构和结构中，固有的系统冗余可以有效地利用，以减轻潜在的渐进倒塌情况。整个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尚未开发的应用，在这些地区，抗震设计的考虑不那么重要。这一过程的第一步是开发合理放松昂贵的钢板剪力墙细节要求的方法，这些要求被认为是规范和标准所必需的，以达到非常高的延展性和循环稳健性。作为实现总体计划目标的重大进展，本研究项目将开发不那么严格的设计要求，应用于低、中震区，并通过相应设计的大规模物理试验在实验室验证其有效性。这项研究项目的成果对加拿大建筑业、建筑设计专业人士和建筑业主的主要好处是，它将为设计钢板剪力墙系统提供一种定义明确的方法，可以经济地利用钢板剪力墙在中、低震区固有的抗震性能，而不需要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.
