組積메움壁의 耐震性 評價에 關한 硏究 = A Study on the Earthquake-Proof Evaluation of Masonry Infilled Wall Frame

다국어 초록 (Multilingual Abstract)

Due to concentration and high density of population, the style of building becomes high rise. Therefore, the buildings require structures such as braces and shearing walls capable to resist various lateral forces caused by wind and earthquake. Domestically, the masonry wall with frame is used as partition walls, which is considerate as a simple wall and the bearing capacity of which is neglected.
It is accepted that when masonry wall and frame interacts each other, the bearing capacity acts to some degree.
In this study, to find the interaction of masonry wall frame, the author selects ten models and to analysis models by finite element method which is used widely in engineering method.
The author has studied rigidity contribution of wall and the ratio of bearing force increasement to frame.
The equivalent brace is substituted for in filled masonry wall and is compared with the existing method.
The results are as follows.
1. When masonry Wall and frame interacts each other, horizontal rigidity of frame increases remarkably.
2. When the ratio of length/height (L/H) of masonry wall become larger, horizontal rigidity increases, deflection decrease by the equivalent diagonal strut.
3. In case the ratio of length/height (L/H) below 0.5, the establishment of girder at an interval of H/2 effects in increasement of horizontal rigidity of frame.
