| 摘 要： | 粘贴加固所需要的材料用量有一个限值,超过这个限值其粘贴加固所用的材料并不能够得到充分利用.在2004年发表的有关文献中,通过对钢筋混凝土受弯构件粘贴加固时加固材料的最大用量进行了理论研究,推导了相应公式,给出了有关图表.现通过对4根粘钢加固钢筋混凝土梁和2根对比梁的破坏试验,验证了有关文献中提出的加固材料最大利用量的计算公式的正确性.并且在试验基础上,对于加固试件的承载力和有效的加固方案进行了具体的分析.

| Abstract: | The quantity of externally bonded strengthened materials has a limitation. The materials could not be used fully if it is beyond. The authors have done a theoretical study on the maximum quantity of externally bonded strengthening materials of reinforced concrete flexural members and have given some formulas and tables for calculating the maximum quantity. In this paper, four of R.C. beams glued with steel plate and two ordinary R.C. beams for comparison have been tested for demonstrating the formulas of maximum quantity which was suggested in article 10]. On the base of the test and analysis, the bearing capacity of externally bonded strengthened beams and effective strengthened schemes are also discussed. |
