Abstract
In a multi-storied frame building, a controlled frame member having means to damp seismic forces of deformation. A first vertical wall column has a top connected to a horizontal wall girder overhanging the wall column. A second wall column is erected in vertical alignment beneath the tip end of the wall girder co-planar with, but spaced from, the first wall column. A seismic response control apparatus connected between the tip end of the wall girder and the top of the second wall column generates damping force when the tip end of the wall girder and the top of the second wall column are displaced relative to each other. Additional girders are arranged on lower stories of the building as required to further strengthen the building against seismic deformation.
