| Outline of Final Research Achievements |
In this study, we are focused on the structural performance of side columns of the RC building with soft 1st story designed on the assumption of different failure modes.
As it is recognized that especially for multistory RC frame buildings with soft story, it is important to evaluate seismic performance of soft story columns. We tested two different failure modes, flexural yielding in the soft story columns and flexure fracture mechanism in a whole frame by yielding the whole reinforcement of the tensioned side of the column in the soft story. In the tests, two loading systems of RC specimens represent side columns of the first soft story floor. As a result, we confirmed that the assumption of distribution of seismic forces are important to design RC frame building especially designed by flexure fracture mechanism in a whole frame. And also, structural performances of side columns, which effect to seismic response to the whole frame, were elucidated.
