| Outline of Final Research Achievements |
A seismic reinforcement method using interlocking bricks was studied. I-shaped bricks was found to be brittle due to stress concentration and strength of masonry wall was not increased. By introducing wave-shaped interlocking bricks, stress concentration was reduced and strength was improved.
The horizontal load imitating seismic force was applied with three kinds of vertical loads. The vertical loads corresponding to 2-story, 4-story and 6-story buildings were considered. As for the 2-story vertical load case, wave-shaped masonry wall had the largest strength and rectangular masonry wall had the least strength. As for the 6-story vertical load case, the strength of rectangular masonry wall increased since the friction force increased. It was found that the wave-shaped masonry brick wall is especially effective for low-story buildings with small vertical load.
