某高层建筑结构动力特性研究

Study on the Dynamic Properties of A Tall Building Structure

利用有限元分析软件ANSYS对某高层建筑结构进行模态分析,建立高层建筑结构的三维模型,研究该结构的动力特性,并将计算得到结构的自振周期同经验公式比较,探讨计算高层建筑结构自振周期的影响因素,结果表明两种计算方法结果十分接近,验证了有限元分析的正确性。

The model of a tall building structure is analyzed by using ANSYS Finite element analysis soft ware. Through its 3- D model, its dynamic properties are studied. And The result is compared to the result by using empirical formula. The influential factor on natural period of vibration of the tall building is discussed. The results show that the calculation is similar, and the method of finite element analysis is right.
