摘　　要：通过对钢筋混凝土Ｔ型梁采用玻璃钢片材及玻璃钢板材两种加固方法的试验，得出了二者对梁抗弯能力和刚度提高的作用及二者差别，最后通过分析并参考《混凝土结构设计规范》，提出了各自实用的计算公式，为今后在实际工程中将这两种新材料用于房屋加固中作了探讨。Through the experiment on the concrete T beam improved by using two methods, ie, sheet of glass fiber reinforced plastics and planking of glass fiber reinforced plastics, this paper shows the improvement effect on the beam antibending copability, analyses the difference between the above two methods, and also, based on the analysis and ″Specification for design of concrete structure″ presents practical formulae respectively which are the exploration for the afterward engineering practice.
