摘要
利用大型有限元分析软件ANSYS对钢筋混凝土高层框筒结构进行模态分析,求出其前5阶固有频率和固有振型,并与理论解进行比较。结果表明,采用大型通用有限元软件ANSYS对钢筋混凝土高层框筒结构的动力分析是可靠的,基于有限元的数值仿真可为实际工程提供借鉴。
The modal analysis frame tube structure has been of high-rise reinforced concrete studied in this paper. The first fifth-order frequencies were acquired based on the famous finite element software-ANSYS. By comparison the results of this paper with the theoretical results, the conclusion can be concluded that; it is reliable using the finite element software ANSYS to analyze the dynamic analysis for high-rise reinforced concrete frame tube structure and the numerical simulation technique based on finite element method will be very useful in practice.
