木造軸組構法における柱脚接合部に入力される引張力に関する研究

Abstract

This monograph relates tension of a column bases in adjustment between an experimental result and calculation by the standard or general design for conventional wooden structure. At first, 2-stories and 126 m^2 model house was given static load to examine the experimental measure and then 2 stories and 27 m^2 square houses was loaded in the same condition to investigate an effect of perpendicular walls to the load direction. Furthermore, some partial models of columns and sills were experimented to clarify the effect of rocking of column and confining of joint. After the experiments, the experimental measurement was revised with the effect of the rocking and confining, and compared with the standard calculation. As a conclusion, when the story deformation angle is 1/50rad. the rocking considerably affects the tension of column bases. The tension is not serious on every column base in the elastic limit. The required value of tension of corner columns seems to be unreasonable, but there is a noteworthy case that the tension more than the required value occurs to the column bases with compressive braces. The perpendicular walls shared with the corner columns seem to carry 1/3 to 1/2 of stress if it has the same specification as the walls in the same direction as the load.
