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，主要基于对其在强震作用下的预期性能的研究而发展到高级阶段。虽然不可否认，该系统非常适合于高地震区，但其他重要的潜在应用在很大程度上被忽略了，例如用于保护结构、工业结构和可以有效利用固有系统冗余来缓解潜在的渐进性倒塌情况的结构。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的未开发应用，这些地区的抗震设计考虑不那么重要。这一过程的第一步是开发合理地放宽钢板剪力墙昂贵的细节要求的方法，规范和标准认为这些要求是实现非常高的延性和循环健壮性所必需的。作为实现总体规划目标的一项重大进展，在本研究项目期间将制定不那么严格的设计要求，用于中低地震区，并将在实验室通过相应设计的大型物理试验来验证其有效性。这一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将是一种明确的方法，可以经济地设计钢板剪力墙体系，以利用其在中低地震区的固有抗震性能，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.
