摘要
通过对渡槽水体计算模型的进一步简化,提出晃动液体的简化模型用于屋顶水箱的计算分析。通过自由复位和地震时程分析,得出简化模型与SPH方法的计算结果基本一致。通过多遇地震时程分析,未经减振设计的偏置水箱有控模型与无控模型相比,对主体结构顶点的位移及顶层位移比有略微减小的作用,对主体结构顶点的加速度有略微增大的作用;罕遇地震作用下,对主体结构顶点的位移及顶层位移比有略微减小的作用,对主体结构的损伤基本相当,但对主体结构顶点的加速度有较大增大的作用。
Through further simplifying the calculation model of water body in the aqueduct,a simplified model of sloshing liquid is proposed for the calculation and analysis of the roof water tank.Through free reset and seismic time history analysis,it is concluded that the calculation results of the simplified model are basically in agreement with those of the SPH method.According to the time history analysis of frequent earthquakes,compared with the uncontrolled model,the controlled model of eccentricity located water tank without anti-vibration design has slightly reduced the displacement of the structure's top floor vertex and the displacement ratio of the top floor,and slightly increased the acceleration of the structure's top floor vertex.Under rare earthquakes,the displacement of the structure's top floor vertex and the displacement ratio of the top floor are slightly reduced,and the damage to the structure is basically the same,but the acceleration of the structure's top floor vertex is greatly increased.
