【摘要】 基于ADINA软件提供的流固耦合模块,采用软件中的势流体单元模拟水体,构建了简化的塔体地基水体有限元动力分析二维模型,并对其施加人工地震波分析了塔体内外的动水压力分布规律,比较了塔内外最大动水压力计算值与理论值。结果表明,该方法对高耸塔体结构的抗震设计有一定参考作用。更多还原

【Abstract】 Based on the fluid-solid coupling module of ADINA,the tower-foundation-water body finite element dynamic analysis model is established by using potential fluid element in ADINA to simulate water body.The distribution of hydrodynamic pressure inside and outside of the intake tower is studied with exerting artificial seismic wave.Then the maximum calculated value of hydrodynamic pressure is compared with the theoretical value.The results show that the method provides reference for aseismic design of high-rise tower body structure.更多还原
