| 摘 要： | 通过对一栋5层未加固与CFRP(碳纤维复合材料)加固的钢筋混凝土框架结构的非线性有限元分析,研究该钢筋混凝土框架的模态性能。模态分析结果表明:CFRP加固对于框架的固有频率影响明显,且增大了结构的刚度,但对振型影响不明显。

| Abstract: | A nonlinear finite element method is used to analyze the modal property of a five-storey RC frame structure with and without CFRP.It is shown that CFRP influences obviously on the natural frequency,and increases stiffness of the structure,but it does not influence on vibration mode from the results of model analyses. |
