Research and Development of an Optimum Device to Reduce Seismic Structural Pounding Damage

在剧烈地震中，相邻建筑物的冲击或动态冲击已被确定为造成破坏的主要原因。由于在地震事件中冲击对结构和非结构造成严重的潜在破坏，因此需要有效的方法和技术来减轻这种影响。提出的研究旨在为位于拥挤的城市中心的相邻建筑物开发减振装置（PRDs）。将考虑系统地处理受冲击的现有建筑物的性质和力学知识中的不确定性，以及预测未来地震的地面运动。这些不确定性将在优化所建议的珠三角部件的机械性能方面发挥重要作用。本研究将调查安装pdr的经济可行性，开发有前途的机械设计概念，模型应用和分析方法。此外，还重点研究了设备硬件规格的制定和安装方法。

The impact, or dynamic pounding, of adjacent buildings has been identified as a major cause of damage during severe earthquakes. Because of the serious potential of structural and nonstructural damage by pounding during seismic events, efficient methods and techniques to mitigate this impact are needed. The proposed research is aimed at the development of pounding reduction devices (PRDs) for adjacent buildings located in congested urban centers. Consideration will be given to the systematic treatment of uncertainties in the knowledge of the properties and mechanics of existing buildings subject to pounding and in predicting future earthquake ground motions. These uncertainties will play an important role in optimizing the mechanical properties of the proposed PRD components. This research will investigate the economic feasibility of installing PDRs, developing promising mechanical design concepts, a model application, and analysis methods. In addition the research focuses on the development of hardware specifications for the devices and methods of installation.
