摘　　要：根据在役结构的“后验性”、时变性,“耐久性”特点,针对目前我国在城市改造与抗震 加固中出现的在役结构后续使用期(后役期)防御烈度形式:等烈度、等超越概率、等发生率 方法,详细分析了它们的风险特点,并提出了作者的看法．According to difference in the characteristics of the existing structure from design structure, this paper defines the defense intensity of the existing construction during succeed use period. In order to strengthen antiseismic administration in reconstruction city at present, some decision method, such as method of equal intensity, method of equal exceed probability, method of equal occurrence ratio, for defense intensity in succeed use period of existing construction were provided. It is useful for the discussion on increase of antiseismic standard （defense intensity） on city, variation of building-function and the antiseismic endurance of construction.
