摘要

利用ANSYS有限元分析软件,建立了等肢异型柱、不等肢异型柱和底层加支撑的等肢异型柱三种不同异形柱框架结构的空间分析模型,对模型输入天津波,采用时程分析法对比分析了三种异形柱框架结构在水平地震作用下的受力和变形特性。计算结果分析表明:加大异型柱肢长可以提高结构抗震性能但作用不十分明显,而加支撑使结构抗震性能明显改善。
By using finite element software ANSYS,the paper has built analysis models of three type of special-shaped column frame,including the equal limb special-shaped column frame,inequiaxial special-shaped column frame,and the equal limb special-shaped column with support in the bottom.Importing tianjin wave,it compares and analyzes the internal force distribution and variability characteristics of three type of structures with time-history domain method.Some conclusions are reached: enhancing the limb of the special-shaped column can often improve the aseismatic performance of special-shaped column frame structure,but the effect is not obvious,however,adding supporting in the bottom can improve the aseismatic performance of special-shaped column frame structure effectively.
