随着地震区划和抗震设计规范的修订,自然会提出这样的问题一建造于烈度提高地区的建筑物和按旧规范建造的建筑物在地震中是否安全的问题,即提出了现有建筑物抗震加固和某一地区震害预测的问题.而这些问题的解决都有赖于对现有建筑物抗震性能的鉴定.本文主要通过实例来说明如何对钢筋混凝土结构进行抗震鉴定. With the revision of the earthquake zone design and seismic design code, it will naturally raise the question of whether buildings built in areas with increased intensity and buildings constructed in accordance with the old code are safe in earthquakes, that is, earthquake resistance of existing buildings is proposed. Reinforcement and earthquake damage prediction in a certain area. The solution to these problems depends on the identification of the seismic performance of existing buildings. This paper mainly explains how to perform seismic evaluation of reinforced concrete structures through examples.
