SHEAR STRENGTHENING OF REINFORCED CONCRETE FRAMED SHEAR WALLS USING CFRP STRIPS

摘要：

The seismic performance of reinforced concrete framed shear walls strengthening with Carbon Fiber Reinforced Polymer (CFRP) strips was quantitatively investigated in this study. The epoxy-bonded CFRP was placed in the diagonal positions in shear walls for shear strengthening. Six large-scale framed shear walls were tested. The results show that the seismic performance of low-rise shear walls strengthening with CFRP strips was significantly enhanced. However, the enhancement of mid-rise shear walls was insignificant. In addition, the improvement of the failure specimen directly retrofitted with CFRP strips was minor. This study is expected to generate both the scientific knowledge and the engineering method in the infrastructure.
