This article provides the useful data information on multiscale modeling of liquid storage laminated composite cylindrical tank under seismic load. The investigation process is divided into three levels. Within the numerical homogenization, the hexagonal microstructure one-eighth and full RVE model is assumed on micro-scale level. Homogenization of unidirectional lamina is done in four steps. For effective material properties of the whole laminate, the laminated representative volume element is assumed on meso-scale level. The numerical homogenization is done by using the Finite Element Method in the program ANSYS. Effective modulus of elasticity is taken into the calculation of internal forces of the laminated composite cylindrical tank on macro-scale level. The base shears bottom of tank wall and tank base, the bending moment above the base plate, and overturning moment bellow the base plate as function of the tank fluid filling are presented. Data inform about seismic response of liquid laminated composite tank during seismic even in Slovak Republic, respecting of Eurocode 8 recommendations.
本文提供了地震荷载作用下液体储存层合复合圆柱罐多尺度建模的有用数据信息。研究过程分为三个层次。在数值均匀化过程中，在微观尺度水平上假设了六边形微观结构的八分之一和完整代表性体积单元（RVE）模型。单向层合板的均匀化分四个步骤进行。对于整个层合板的有效材料性能，在细观尺度水平上假设了层合代表性体积单元。数值均匀化通过ANSYS程序中的有限元法完成。有效弹性模量用于宏观尺度上层合复合圆柱罐内力的计算。给出了罐壁底部和罐底的基础剪力、底板上方的弯矩以及底板下方的倾覆弯矩随罐内液体充装量的变化情况。数据说明了斯洛伐克共和国液体层合复合罐在地震事件中的地震响应，符合欧洲规范8的建议。
