随着抗震技术的进步和社会经济发展水平的提升，抗震设计应逐步由抗倒塌设计向可恢复功能设计转变。可恢复功能结构是目前抗震领域的研究热点，也是未来抗震的重要发展方向。传统的抗震结构强调结构的延性，良好的延性和足够的承载力虽能避免结构在强震时产生倒塌，但往往会对结构造成较大的损伤，震后较难修复或代价昂贵。With the advancement of anti-seismic technology and the improvement of social and economic development level, anti-seismic design should gradually change from anti-collapse design to design of recoverable function. Recoverable functional structure is a research hotspot in the field of earthquake resistance at present, and it is also an important development direction of earthquake resistance in the future. Traditional earthquake-resistant structures emphasize the ductility of the structure. Although good ductility and sufficient bearing capacity can prevent the structure from collapsing during strong earthquakes, it often causes greater damage to the structure, and it is difficult or expensive to repair after the earthquake.
因此，针对高层和超高层建筑结构中广泛使用的筒体结构体系，研制开发一种能够在强震后快速恢复其正常使用功能的可恢复功能筒体结构体系就显得既迫切而且特别有意义。Therefore, for the cylinder structure system widely used in high-rise and super high-rise building structures, it is urgent and particularly meaningful to develop a recoverable functional cylinder structure system that can quickly restore its normal function after a strong earthquake.
