摘要
利用ANSYS有限元分析软件,模拟埋入橡胶层RC柱和普通RC柱的承载力-变形特性以及变形特征,分析结果表明普通RC柱的试验值与有限元分析结果吻合较好,而埋入橡胶层后RC柱的初始刚度较试验值小,但其承载力较试验结果大,说明现有反复加载时橡胶的本构模型很难正确的模拟橡胶的特性,是以后需要继续研究的课题。
Load capacity-displacement behavior and deformation manners of RC columns with rubber layer built-in or not were analyzed with FEM software ANSYS.It can be concluded that the analysis result has a good agreement with that of test for RC column.The initial stiffness of the RC columns with rubber layers built-in were smaller than that of tests,while the ultimate strengths obtained from analysis were larger than that of tests.It showed that the current constitutive model of rubber couldn＇t correctly simulate the properties of rubber material,which are needed to be thoroughly studied in the future.
