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.
