国内有不少地区的建筑都是采用钢筋混凝土建造的,其结构形式也多以框架为主,一些老旧建筑由于各种原因,存在抗震方面的安全隐患,随着人们对建筑抗震性能的关注,这部分老旧建筑也急需进行加固处理。将钢支撑用于多层钢筋混凝土框架结构的加固中,可以增强结构的稳固性与抗侧刚度,使该结构的抗震性能得以明显改善。
In many parts of China, the buildings are made of reinforced concrete. The structure of the buildings is mainly based on the framework. Some old buildings have potential safety problems in earthquake resistance due to various reasons. As people pay attention to the seismic performance of buildings , This part of the old building is also in urgent need of reinforcement. The use of steel support in the reinforcement of multi-story reinforced concrete frame structure can enhance the structural stability and lateral stiffness, so that the seismic performance of the structure can be significantly improved.
