| Research Abstract |
Eight barbell and four L-shaped model wall specimens where the bottom of side column stretches largely were tested to investigate their shear yield strength. It was found that the shear yield strength was smaller than shear ultimate strength under compressive axial stress when shear reinforcement ratio for wall is small or hoop ratio is large. The calculated value by the shear yield strength equation considering dowel action often becomes much larger than the experimental value.
