摘要: 遗产建筑不同于一般建筑,需要通过抗震韧性的维系不断延续生命周期,其抗震评估不能沿用传统的建筑抗震评估策略. 基于遗产建筑抗震韧性基准周期,探讨了遗产建筑抗震评估的特征性表现:在遗产建筑评估过程中,其韧性基准周期的确定与抗震干预技术的选择之间是一个互动的过程,韧性基准周期随着时间的进程允许转换和扩增以获得更强的韧性,而抗震干预技术的可逆性评价在遗产建筑抗震评估体系中将起到不可忽视的作用.

Abstract: Different from general buildings, heritage buildings need to continue their life cycle through the maintenance ofseismic resilience, and their seismic evaluation cannot follow the traditional building seismic evaluation strategy. Thecharacteristic of seismic assessment of heritage buildings through the induction of reference period for seismic resilienceevaluation was studied. In the process of heritage building evaluation, there is an interactive process between thedetermination of resilience reference period and the selection of seismic intervention technology. The resilience referenceperiod allows conversion and amplification over time to obtain stronger resilience, and the reversibility evaluation of seismicintervention technology will play an important role in the seismic evaluation system of heritage buildings.

Keywords: heritage building; seismic resilience; reference period; seismic assessment; reversibility
