六度区建筑物抗震鉴定与抗震加固策略

Quake Evalvation and Quake Strengthening Coordinated Study for Buildings of Earthquake Intensity Area

针对六度区抗震鉴定与抗震加固问题，从工程结构的重要性、结构服役年限、发生地震的超越概率、北方地区建筑结构的特点、加固投入经济效益及社会承受能力等方面综合论述了抗震鉴定及抗震加固应采取的策略，提出了抗震鉴定的图纸鉴定、抗震鉴定计算分析、专家知识鉴定三阶段方法，并以此来指导抗震加固，使加固的经济投入最少．

This paper discusses the coordinated study method of evaluation and quake strength from the point of engineering importance; service years, earthquake occurrence exceeding probability, and the characteristics of north construction. Strengthening economic effort effects society enduring ability for Ⅵ earthquake intensity area. The three step methods of quake evaluation is provided, and depending on this method to direct quake strengthening for engineering. So that quake strengthening effort for engineering is the lowest and society and economic benefit is the largest.
