| Abstract |
In this study, the out-of-plane seismic performance of outer masonry walls strengthened on one side with a steel-bar truss system was
experimentally evaluated. There were three C-shaped specimens with variables that had the presence or absence of reinforcement on both
intersection walls and the door-size opening. The steel-bar truss system used for reinforcement was installed on the inner side of the main
outer wall and both intersecting walls. The peak strength in the positive direction of the specimen reinforcement on both the main and
intersecting walls was approximately 2.3 times higher than that of the other specimen that was reinforced in only the main wall; the two
specimens had similar peak strengths in the negative direction. The peak strength of the specimen with a door-size opening was similar to
the specimen without a door-size opening. Therefore, it was determined that the seismic performance of the masonry wall can be greatly
improved by reinforcing the main and intersecting walls together rather than reinforcing the main wall exclusively. |
