| 摘 要： | 首先简要介绍了预应力混凝土框架火灾试验情况、火灾后采用碳纤维加固试验过程，然后对加固后的混凝土框架进行静力试验．通过对试验结果进行分析．发现加固后的预应力混凝土框架承载力显著提高，延性和整体刚度得到改善，碳纤维能较好地发挥作用。因此碳纤维加固技术是一个值得进一步深入研究的课题。

| Abstract: | In this paper, experiment of prestressed concrete going through high temperature is presented and experiment of prestressed concrete frame rehabilitated by CRFP is test. The results are analyzed. It is found that after reinforcement the ultimate strength and ductility of prestressed concrete frame are greatly enhanced. So such technique is a significant one which deserves further investigation. |
