| 摘 要： | FRP片材加固混凝土结构的应用与研究已取得了很多的成果，而用FRP型材加固混凝土结构的研究则不多见。文章将CFRP、GFRP复合型工字截面型材应用于单向板的加固，通过简化理论分析和有限元计算方法，探讨了FRP型材加固混凝土板的可能性，并根据板在不同加固方式下强度、刚度等方面的性能比较，揭示了这种加固方式的特点。

| Abstract: | Many achievements about the effects of retrofitting the concrete structures with FRP sheets have been reached, however, the researches on using FPR shapes to strengthen the concrete structures are not widely conducted. This paper utilized CFRP and GFRP composite I - shapes to reinforce the one - way concrete slabs, and discussed the probability of this method through theoretical analysis and the results of FEM calculation. After comparing the specialties of reinforced slabs in aspect of strength, stiffness by different strengthening methods, the properties of strengthening the slabs with FRP I - shapes are presented. |
