抄録: The problem of the vibrations of a framed structure due to seismic waves has already been studied theoretically by many authors. But in their treatments, it is mainly to assumed that the fixing between the horizontal members and the vertical members of a structure are either in perfectly clamped condition or in perfectly hinged one. The actual conditions in question of a framed structure, especially of a Japanese-style building, are indeed generally so complex that the treatment of the problem rigorously is difficult. In the present case, the idea as to the condition of fixing is such an intermediate one that the bending moment of the column at the joint is proportional to the inclination at the same joint. Furthermore, we investigated mathematically relatively simple cases, namely, the case in which the upper end of a column is free and the lower end is in the condition shown in the above idea, and the case, in which a single-storied and mono-spanned structure with upper joints perfectly fixed and lower joints in the condition shown in the idea just given. On the other hand, we have also conducted experiments with a model having tenon connection(hozo). This tenon connection is a part causing serious damages to a Japanese wooden building. Comparing the experimental results with the mathematical calculations, it was found that both results fairly agree in vibration modes as well as in natural vibration periods.
