【提要】  对现有建筑的加固改造中遇到的后续设计使用年限的确定、现有结构的可靠性鉴定和抗震鉴
定、改造要求与设计和技术及经济的协调、新技术应用等问题进行讨论，建议可采用不同的后续设计使用年限和相应的设防标准，提出了用“综合性能指数”和“综合决策指数”使加固改造的决策相对定量化的构思。最后还给出了工程应用实例予以验证。

Comprehensive Strategic Method and Application for Strengthening and Retrofit of Existing Building Structures/Dai Guoying(China Academy of Building Research, Beijing 100013, China)Abstract:For the strengthening and retrofit of existing buildings, the seismic fortification criterion corresponding to diverse successive design working life has been proposed, and aquantifiable judgment method has been described.The index of comprehensive performance and index of comprehensive strategy are put forward, and then the comparison between different strengthening and retrofit method may use their numerical value. An applied example has been shown.
