| Outline of Final Research Achievements |
The effect of intersecting walls on seismic performance of bearing walls in partially grouted concrete masonry buildings is investigated experimentally. The test results indicated that the intersecting walls increase the ultimate shear strength as well as deformation capacity of the walls. Also, we proposed a seismic retrofit method for existing partially grouted concrete masonry walls with polymer-cement mortar, PCM, and conducted a lateral loading test for the walls. The test results demonstrate that the application of reinforced PCM overlay provides significantly higher lateral load-carrying capacity to the wall.
A simplified expression of the ultimate shearing stresses for different bearing walls, which can be used for approximate evaluation of lateral load-carrying capacity for existing buildings, was obtained.
