摘要
以理论分析和ANSYS有限元分析为主要手段,对构件进行了屈曲分析和非线性分析,研究了CGFRP加固圆管受压柱的受力性能,结果显示CGFRP加固圆管受压柱的稳定承载力效果比较明显,特别适合初始弯曲率和宽厚比较大的构件,此外,提出针对该类构件的理论简化计算模型,将理论计算结果与ANSYS有限元分析结果进行比较,分析了二者出现差异的原因。
Mechanical performance of CGFRP reinforce pipe compressed column is studied, by buckling analysis and nonlinear analysis, with theoretical analysis and ANSYS finite element analysis being the main means. The results show that bearing capaeity of structures that pasted with CGFRP is improved significantly, especially for these structures with big initial bending and big width-to-thickness ratio. Besides, simpli- fied calculation model is proposed and calculation results are compared with finite element analysis results and reasons of the differenee.
