抄録: When a framed structure that is apparently of two-dimensional form, oscillates in the direction normal to the plane of that structure, the vibration becomes a three-dimensional one for certain conditions of the columns and beams. In the present case, we studied the forced vibration of a single-storied structure of two-spans with damping inner resistance. From the results of the present investigation we found that when a broad house with weak columns in its middle part is subjected to destructive seismic disturbance transverse to the broad side, the same house is damaged mostly at the weak middle part in question. On the other hand, from the present investigation, we have ascertained that if a damping inner resistance exists in a structure, the middle thick column is effective both in reducing the bending moment of every column and in increasing the natural frequency of the structure. The bending moment at the lower end of every column is, at least, a few times greater than that at the panel point of the same column.
