摘要
对于钢筋混凝土环梁基础上的大型储罐,当承受液体静压时,罐底板与最底层罐壁板连接处的应力状态十分复杂。文章按弹性地基梁假设,采用ANSYS有限元计算软件提供的双线性杆单元(LINK10单元)等效替代罐底的单向弹性基础,对其进行有限元应力分析,得到了较为精确和直观的计算结果。
regarding to large-scaled storage tank laid down onto reinforced concrete cycle beam foundation(RC cycle foundation in abbre-viation),the stress situation between the tank bottom plate and lowest tank wall plate is extremely complicated when the tank is under static pressure of liquid.More precise stress analysis on this high stressed zone has not currently been seen reported so far.Basing on as-sume of elastic foundation,the paper adopts double linear rod unit provided by ANSYS finite element calculated software(LINK10unit)to equivalently replace unidirectional elastic foundation and undertakes finite element stress analysis on it,thus more accurate and objective calculated result can be gained.
