| Abstract | We report the progress of an experimental study conducted to understand the seismic performance of a timber columnground sill joint reinforced using an aramid fiber sheet, and to improve the deformation property of the reinforced joint. An aramid fiber sheet is a new material that weaves high-performance aramid fibers in one or two directions. In previous research, certain problems were found: (a) even when applying a similar reinforcement, the sheet did not necessarily demonstrate the same failure mode, and (b) when the sheet was peeled off in stretches, the joint is destroyed through brittleness. In this study, based on the preceding research, we proposed a new sheetpasting method for an improvement in the deformation property, and conducted a bending test under cyclic loading for some columnground sill joint specimens to verify the seismic performance and failure behavior. It was found that, by splitting the sheet, the problems of the preceding research are avoidable. |
