【摘要】 基于某水电站厂房钢管混凝土排架结构受力特点和变形规律,建立了包括上下部结构的整体机组段三维精细有限元分析模型,利用ADINA的约束方程分析了钢管混凝土排架结构与上部屋顶和吊车梁不同连接方式对排架结构受力性能的影响,并采用振型分解反应谱法研究了不同连接方式下对排架结构动力特性的影响。研究方法与结果可为工程设计提供参考。更多还原

【Abstract】 With regard to the stress characteristics and deformation rules of concrete filled steel tube bent structure of hydropower station,a fine 3D finite element model of the whole generator block for upper and lower workshop is established.The constraint equations of ADINA is applied to analyze the effect of concrete filled steel tube mechanical behavior in different connection way with the upper roof and crane beam.And the mode decomposition response spectrum method is used to study the effect of bent structure dynamic characteristics in different connection way.Methods and results of this paper can provide reference for engineering design.更多还原
