摘　　要：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。Reinforced concrete is adopted in building construction in many regions of China with frame as the major structural style.Due to varied reasons,safety issues on earthquake resistance may occur to some old buildings.As people become aware of the construction＇s performance on earthquake resistance,it is urgent to strengthen these old buildings.The application of steel bracing to the multilayer reinforced concrete frame structure to achieve strengthening effect can enhance the structural stability and the lateral stiffness,which will dramatically improve the earthquake resistant performance of the structure.
