摘　　要：以乌鲁木齐市某中学七层(地上六层,地下一层)钢筋混凝土框架结构为例,使用SAP2000对该中学进行消能减震加固分析,用附加非线性阻尼单元模拟粘滞阻尼器。通过分析,加固后,多遇地震时,结构层剪力、层间位移角较加固前均有显著减小;大震时,层间最大位移角也能显著减小;两种情况下的位移角均由不满足现行规范变为满足规范。Taking a seven layers middle school in urumqi （The ground six layers, underground one layer） reinforced concrete frame structure as an example, making use of SAP2000 to analyse the earth- quake-reduction of the strengthened building, with additional nonlinear damping unit to imitate viscous damper. Through the analysis results, the building was reinforced performanced as follows：when in the frequently encountered earthquake, shear force and displacement angle of the structure layer were minished significantly, as well as the largest displacement angle when the building performanced in the rarely earthquake ; these two cases of displacement angle could meet the existing standard from dissatisfying the standard.
