水电站地面厂房上部结构抗振分析
Anti-Vibration Analysis of Upper Ground Powerhouse Structure for Hydropower Projects
摘要
Abstract
Taking a ground powerhouse structure for hydropower station for an example,the structure of the numerical model was established by using large finite element software to check the influence of project and the size. The reason for this is because the upper structure is in low stiffness relatively. First this paper conducted the calculation and analysis of the upper structure under the static and dynamic load,comparing all kinds of case calculation results,thus stiffness and strength characteristic were analyzed in the view of the static angle. And then to the natural vibration properties of the upper structure,and the vibration of structure under the unit dynamic load and the earthquake response spectrum analysis,from this respect the vibration characteristic was checked in the point of view of dynamic analysis. It is proved that increasing wall-structure can improve the anti-vibration performance and integrated vibration analysis results show that using column-shear wall is more advantageous.关键词
