A Study on flexural bearing capacity of RC Beams combination strengthened with CFRP by Comparative Experiments Chen Xiaoqiang1, a, Jia Bin1, b, Yao Huachuan1, c, Zhang Yu1 1Department of Civil Engineering and Architecture, Southwest University of Science and Technology, Mianyang, 621010, China aChenxiaoqiang@swust.conl, bJiabin216@126.com, c369770836@qq.com Keywords: CFRP, Replacing concrete, Plating bar, RC beam Abstract: This paper compares the flexural bearing capacity, rigidity, and ductility of the reinforced RC beams after comparative tests of reinforcing RC beams by three different ways: directly bonding CFRP, bonding CFRP after replacing concrete and bonding CFRP after replacing concrete and planting bar.
Brief introduction of replacing concrete The Local Replacement Technology of Concrete Member uses the high-strength concrete or grouting material to replace the concrete with quality defects in the original structural components.

But certain differences exist in materials smelting, machining, heat treatment and other aspects between domestic materials gear and ISO6336-1996 test gears[4-8].
The main idea is: there is a certain life of metal materials under alternating stress, and each time of alternating stress causes a small amount of damage.

As the transmutation products of H and He will induce irradiation damage, which may change the microstructure and mechanical properties of structural materials, it is necessary to study on this issue .
Though the effects of single H or He irradiation damage on the materials’ properties have been studied for many years[5-8], there are few reports of He/H ion co-implantation effect on ODS ferritic steels [9,10].
