摘要
本文把储液罐罐顶简化为固定剪切梁端部一集中质量,根据变分原理,用黑兹法求出其固有振型,按地震谱理论计算了液动压力的分布。计算结果表明,罐顶质量对储罐中液体的液动压力分布和大小都影响不大。
In the paper the roof of a tank storaged liquid is simplyfied as an end of a fixed shear beam with lumped mass. According to the principle of variants the intrinsic vibration type was found by the Heizi method,and the distribution of dynamic liquid pressure is calculated by the seismic spectrum theory. The results show that the mass of tank roof gives less effect on the distribution and magnitude of dynamic liquid pressure.
