摘 要:为了研究纳米SiO2掺量对混杂纤维混凝土结构抗震性能的影响,建立弹性约束和固定约束相结合的模型,综合运用结构动力学分析方法,应用ANSYS WORKBENCH有限元分析软件,采用美国EI-Centro南北方向振动加速度,进行地震响应分析计算。根据求解云图,发现掺量为总质量0.36%的纳米SiO2混杂纤维混凝土抗震效果最好,相对于不掺纳米SiO2的混凝土形变位移减小3.4%~3.6%。
Abstract: In order to study the influence of nano-SiO2 content on the seismic performance of hybrid fiber concrete structure, the seismic response analysis was carried out with the established model of elastic restraint and fixed constraint using the finite element analysis software ANSYS WORKBENCH, in which the structural dynamic analysis method and the EI-Centro vibration acceleration in north and south direction have been used. According to the solution of the cloud map, the best seismic performance has been found with adding 0.36% nano-SiO2 to the hybrid fiber concrete, when the deformation displacement reduced 3.4%~3.6% with no nano-SiO2.
