地震作用下石油储罐浮顶强度及稳定性分析

ANALYSIS OF STRENGTH AND STEADY PROPERTY IN THE FLOATING ROOF OF THE OIL STORAGE TANK UNDER THE ACTION OF EARTHQUAKE FORCE

分析了石油储罐在地震波作用下单盘浮顶的运动状态 ,提出单盘浮顶在地震波作用下的力学模型 ,并应用薄板大挠度理论 ,采用边界元法求解单盘浮顶的边缘膜应力 .在这一基础上对浮顶的强度及稳定性作了进一步分析 .

After analyzing the motion of the floating roof on the oil storage tank during an earthquake,a mechanical model of the floating roof during the earthquake is suggested in this paper.The boundary membranous stress of the floating roof is analysed by the boundary element method,and then discussing its strength and steady property.
