摘要
本文简要介绍了9个用碳纤维加固的混凝土梁板柱节点低周反复试验的情况,对试验结果进 行了分析,发现加固后的节点极限承载力和抗震性能都有大幅度的提高,各项性能指标都达到并超过了 我国现行抗震规范的要求,因此碳纤维加固混凝土节点技术是一个值得进一步深入研究的课题。
In this paper, nine beam-column-slab connections are tested under low frequency reversed load. The results are analyzed. It is found that after strengthening by CFRP the ultimate strength and aseismatic behavior of joints are greatly enhanced. Almost all of the behaviors of strengthened joints exceed the requirement raised by current code. So such technique is a significant one which is deserved to be further investigated.
