建筑物内大体积水体的地震动力响应及对主体结构的影响

Seismic dynamic reaction and its effect on the main structure of large volume water inside buildings

建筑物内大型水体的动力响应分析以及对结构的影响是建筑结构中较少遇到的问题。参考了国内外现有的构筑物规范,采用了流体分析的基本假定,考虑了流固耦合作用,用Fluent软件对建筑内的大型水体部分进行了地震波输入下的动力分析,对结构。分析结果表明,建筑物内一定尺度的大体积水体按其惯性质量进行动力分析对结构是偏于安全的。

It is scarcely to analyze seismic dynamic reaction and its effect on the main structure of large volume water inside buildings.Based on fluid assumption,considering fluid-structure interaction,seismic dynamic reaction of the large water is analyzed using fluent software.It is safe to consider the large volume water inside buildings as the inertia mass.
