【摘要】 利用玄武岩纤维布对九层框架的梁柱节点进行了加固,运用ANSYS有限元分析软件对不同加固方案下结构的整体抗震性能进行了动力分析.分析结果表明,在玄武岩纤维布用料相同的条件下,局部加固框架的角柱节点比边柱节点更有助于提高框架结构的抗震能力,且在地震作用下,采取整体加固的方案更有助于提高框架结构的安全性.更多还原

【Abstract】 The beam-column joints of a nine-layered frame are strengthened with basalt fiber cloth,and a dynamic analysis of the overall seismic behavior of the structure under different reinforcement schemes is carried out by using ANSYS finite element analysis software. The analysis results show that,when using the same basalt fiber cloth material,compared with the side column joints,the corner column joints of the local reinforcement frame is more helpful to improve the seismic behavior of the frame structure;and during earthquake,taking the overall reinforcement scheme is more helpful to improve the safety of the frame structure.更多还原
