混凝土梁在不同复合材料加固下的性能试验研究

EXPERIMENTAL RESEARCH ON PROPERTY OF REINFORCED CONCRETE BEAM STRENGTHENED BY DIFFERENT COMPOSITE MATERIALS

通过对钢筋混凝土Ｔ 型梁采用三面围覆玻璃钢片材和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间的差别，最后通过分析并参考《混凝土结构设计规范》（ＧＢＪ１０－ ８９），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索。

Through the tests of the reinforced concrete T beams strengthened respectively with a method of three side enveloping fibreglass reinforced plastics (FRP) films and that of FRP plates,the effects of these methods on the bending capacity and the increase in stiffness of T beams as well as the difference between them were obtained.Finally,the practical calculation formulas for each of the methods were proposed using theoretical analysis and by reference to “The Code of Concrete Structure Design” (GBJ10-89).Explorations were also made to use these new materials for strengthening buildings in the future practice.
