【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.更多还原

【Abstract】 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.更多还原
