[Abstract]:Since the founding of New China, due to the backward level of science and technology at that time, the limited economic level and the lack of understanding of the seriousness of the earthquake and the importance of aseismic buildings, The seismic design of buildings has not been well implemented. With the rapid development of high-rise buildings, new technologies and materials for seismic strengthening of structures, The study of the new method has become an important work in the future construction development and earthquake prevention and mitigation in our country. In this paper, the new technology of seismic energy dissipation reinforcement is applied to the seismic strengthening design of existing high-rise buildings. Combining the new technology of isolation and energy dissipation with the evaluation of seismic structure performance, an effective solution is proposed for the seismic strengthening design of building structures in China. In this paper, based on the catastrophe chain theory, the mechanism of earthquake energy propagation and evolution in medium carrier is summarized and analyzed from the angle of energy chain deduction, and the chain evolution relationship of seismic energy is studied. The energy transformation metric analysis model is established by using catastrophe chain theory to analyze the relationship between the quantitative change and the qualitative change of the energy chain evolution and the material primary relationship of the energy chain evolution. This paper studies the model of energy propagation and evolution in medium carrier under the action of ground motion, and puts forward the relationship between earthquake disaster induction and medium carrier shape change, which has certain theoretical significance and value in deepening the understanding of earthquake action. Based on the optimum design method of seismic performance of structures, The design of additional dampers for energy dissipation is proposed based on the capacity spectrum method of static elastic-plastic analysis. The design of energy dissipation measures for reinforced concrete frame structures with viscous dampers is carried out through an engineering example. The finite element software Midas/Gen is used to design and analyze the high-rise frame structure, and the seismic performance of the structure is evaluated, including the vibration response spectrum of the structure and the static elastic-plastic analysis of the structure. The analysis results of capacity spectrum and demand spectrum curve, displacement and displacement angle under different load conditions are obtained. The seismic performance target of the structure is judged by capacity spectrum method, and the viscous damping coefficient is distributed in the model with uniform layout mode. Finally, the effects of energy dissipation and seismic absorption of structures before and after damping are compared, which provides reference and reference for the seismic reinforcement design of existing high-rise building structures.
