초록

The purpose of this study is to evaluate the flexural behavior of flexural retrofitted shear walls connected to slabs retrofitted with vertical rebar after wall end crushing. The main variable was the application of the flexural retrofit method. The evaluation of the effect of the shear studs when the retrofit method was applied was intentionally constructed with 60% of the actual required number. As a result of this experiment, it was possible to confirm the strength increase of about 56% with the flexural retrofit. As suggested in the previous study, the retrofitted wall and the existing wall exhibited partial composite behavior, which resulted in the deformation of the slab and the phenomenon of the concrete covering falling off. Double curvature appeared as a strain on the upper part of the wall when it was reversed. The part where the moment was reversed appeared to be the upper part of the wall and not the center. It was confirmed that the damage to the slab was greater when the joint section of the existing wall and the new wall were subjected to tension. Additionally, it was judged that this should be considered when designing the retrofit of the slab and the shear wall.
