| Research Abstract |
In order to clarify the lateral-force resisting mechanisms of flexure-dominant multi-story structural walls, experimentalstudy was conducted with two reinforced concrete specimens with 30% scale. The specimens consisted of the soft first story and the three stories of structural wall from the second floor to the fourth floor. Although the structural walls failed in flexure at the second floor as expected, uniformly distributed drift angle was observed at eachstory. Insufficient flexural strength of boundary beams under the structural walls caused the plastic hinge rotation at the bottom end of columns at the first floor.
