| Abstract: | Based on the resistant to shearing of fourteen reinforced concrete beams ,the effectives of the shear property and designing method of strengthening are studied for the RC beams strengthened with advanced glass-fiber composites .The paper analyzes and discusses the effects varying with different glass-fiber sticking ratios and different strengthening methods. The whole process of the experimental beams are analyzed. The model and formula for calculating the shear capacity and important factors in the strengthening design are put forward on the basis of the experimental results. |
| Keywords: | reinforced concrete beams advanced glass-fiber composites shearing performance strengthening design method |
