摘　　要：基于有限元分析方法,首先建立了锅炉钢构架ANSYS计算模型,对其在强震作用下的地震反应进行了分析.然后,根据锅炉钢构架地震反应的特征安装摩擦阻尼器,对安装摩擦阻尼器锅炉钢构架进行了强震作用下的地震反应分析.计算结果表明控制效果明显,为锅炉钢构架的被动控制提供了理论依据.Based on finite element analysis, set up the model of the boiler steel-structure in the ANSYS and got its response to the strong seism. In according with the response, the boiler steel-structure model was equipped with some friction dampers in some special places. What＇ s more, the response was got. The analysis results indicate that the friction dampers work effectively in the boiler steel-structure. This job offers the theory foundation for the passive control of the boiler steel -structure.
