一、概述 圓柱形储罐乃石油炼厂、工厂、电站以及城市供水系统贮存液体的普通构筑物。在正常环境下,液体以轴对称静水荷载作用于罐壁,在罐壁中只引起环向张力。地震波引起的强烈地面运动,将在储罐液体中引起惯性力,当储罐位于地震区时,必须顾及附加的地震荷载。流体动水压力并非轴对称,可在罐底引起大的剪力和倾覆力矩。一种常见的破坏形式是罐壁
First, an overview Cylindrical storage tank is a common structure of oil refineries, factories, power stations and urban water supply system storage of liquid. Under normal conditions, the liquid acts on the tank wall with an axisymmetric hydrostatic load, causing only hoop tension in the tank wall. Strong ground motion caused by seismic waves will cause inertial forces in the tank liquid and additional seismic loads must be taken into account when the tank is in an earthquake zone. Fluid hydrodynamic pressure is not axisymmetric, can cause large shear and overturning moment in the tank bottom. A common form of damage is the tank wall
