Abstract:
The wooden building skeleton of the present invention has excellent quake resistance because the column of a rigid-frame structure joined to a cross member or the foundation so that a bending moment can be transferred therebetween and the load-bearing wall therein exhibit their load bearing ability. A foundation and a wooden column and the wooden column and a beam are respectively joined by two bolts so that a bending moment can be transferred therebetween. A load-bearing wall is also provided between the beam and the foundation. The length of the section of the bolts which undergoes elongation when inter-story deflection occurs between the beam and the foundation or the cross-sectional dimensions of the wooden column is set such that the inter-story deflection which is generated before the wooden column is fractured is almost equal to or greater than the inter-story deflection which is generated before the load-bearing wall is fractured.
