摘要
根据某水电站厂房钢管混凝土排架结构的受力特点和变形规律,建立了上部厂房组合结构的整体三维动力有限元分析模型,分析了钢管混凝土排架结构的动力特性,给出了排架结构的自振频率.采用Newmark分析方法研究了钢管混凝土排架结构地震响应,给出了水平地震作用下排架结构的应力和位移的变化规律,并对排架柱的抗震性能进行了评价.
With regard to the stress characteristics and deformation rules of concrete filled steel tube bent structure of a hydropower station,a 3D dynamic finite element model of steel-concrete composite structure for upper workshop was established.The dynamic characteristic of the concrete-filled steel tube bent structure was analyzed,and its natural vibration frequency was given.The Newmark analysis method was employed to study the seismic response of the bent structure,and change of the stress and displacement of bent structure was also yielded. The seismic behavior of the bent structure was evaluated.
