±800kV换流站阀厅结构扭转变形分析
Torsion Deformation of Valve Hall Structure in ±800 kV Convertor Station
【摘要】 建立了某±800kV换流站阀厅结构的有限元模型,对挂阀前后的框架剪力墙阀厅结构和全剪力墙阀厅结构进行模态分析,比较了阀厅结构挂阀前后的振型和频率变化,分析了地震作用下阀厅结构的扭转特性。另外,对悬挂阀塔的框架剪力墙阀厅结构和全剪力墙阀厅结构进行了动力时程分析,对2种结构型式阀厅的扭转变形进行了整体评价。
【Abstract】 The finite element models of valve hall structure in ±800 kV convertor station is constructed in the paper.The model analyses of shot-pier shear wall structure and shear wall structure of valve hall are performed.The corresponding frequency and mode of vibration are analyzed,and the torsion deformation is discussed under earthquake wave.In addition,the dynamical and time history analyses of two valve halls are carried out,and the global assessment for torsion deformation discussed.
