ABSTRACT
In the motivation of bringing tons of benefits and positive influences to civil engineering field and society, seismic isolation and energy dissipation systems are of extremely significance in discussion and developing. By researching tons of literature associated with seismic isolation and energy dissipation systems, a newly developed earthquake-resistant structure, from the beginning of the 21st century, this paper summarizes the development, progresses and applications of this technology. Compared with the conventional seismic design, the structural isolation system is a more reasonable, effective, safe and economical damping system. It has significant advantages in the effect of damping controlling, disaster prevention and mitigation, and benefits in terms of society and economy (Xiao et al. 2021). This paper emphatically introduces a variety of commonly used isolation devices and the development status of isolation technology in the world. In addition, this paper compares the conventional seismic design with the isolation design, and briefly introduces what are the advantages of the isolation structure. A model simulation has been performed in SAP2000 to analyse the damping effect of lead rubber bearing isolation and compare the performances of structures with isolators and structures without isolators during an earthquake. Finally, by taking an example of a newly constructed training hall on the north side of the China National Stadium, this paper does a case study and briefly talks about the effective utilization of seismic isolation and energy dissipation systems in real life. Based on the summary of the present situation of structural isolation systems, this paper discusses the future development direction of seismic isolation technology research and its positive influence on the field of civil engineering. Seismic isolation and energy dissipation system is the future trend of earthquake-resistant structures due to several advantages, and the widespread using of this technology is suggested and recommended in contemporary society.
