多目标协同建筑结构消能减震技术研究进展

RESEARCH PROGRESS ON MULTI-OBJECTIVE ENERGY DISSIPATION TECHNOLOGY FOR BUILDING STRUCTURES

  • 摘要: 消能减震技术是提升建筑结构抗震性能的有效手段。随着城乡建设的发展,以“最大层间位移角”作为主要控制目标的传统消能减震技术,逐渐难以满足更综合性、系统性的结构地震安全需求,催生了多目标协同减震技术。该文重点介绍和总结课题组在多目标协同减震技术领域的研究工作,以“结构最大响应与损伤集中协同控制”、“多地震水准响应协同控制”和“结构刚度与耗能能力的协同控制”三种协同减震策略为例,逐一阐述分析协同控制的需求,概括介绍团队提出的协同控制思路和研究进展,并展望多目标协同减震技术未来的发展方向。

     

    Abstract: The energy dissipation and vibration reduction technology are effective means to enhance the seismic performance of building structures. With the development of urban and rural construction, the traditional energy dissipation and vibration reduction technology, which uses the "maximum inter-story drift angle" as the primary control objective, is gradually becoming insufficient to meet the more comprehensive and systematic structural seismic safety requirements. This has given rise to multi-objective energy dissipation technology for building structures. This paper focuses on introducing and summarizing the research work of our team in the field of multi-objective energy dissipation technology for building structures. Using three multi-objective energy dissipation strategies as examples— “collaborative control of maximum structural response and damage concentration,” “collaborative control of multi-seismic level response,” and “collaborative control of structural stiffness and energy dissipation capacity”—we explain and analyze the need for collaborative control, provide a brief overview of the collaborative control concepts proposed by the team, and discuss the progress of the research. Additionally, we offer insights into the future development direction of multi-objective energy dissipation technology for building structures.
