| Research Abstract |
Consideration for seismic perfomance and durability is necessary for the maintenance of the infrastructure structure. Therefore retrofit tests and analysis has been conducted with RC beam models in order to establish strengthening design procedure to existing beam by DFRCC (Ductile Fiber Reinforced Cementitious Composite) U-shaped winding.
Specifically, I carried out durability test, shear test pure bending test and Finite element nonlinear analysis. As a result, I proved the usefulness of the reinforcing effect of RC beam by DFRCC winding. Furthermore practical design equation is conclusively proposed focusing on additional shear capacity increase due to crack width control by DFRCC winding.
