Restrict the beam members to shorter members. As a result, the member is destroyed by the shear force due to the earthquake, prior to the shear failure before the bending failure. Regarding this destruction, a case where the non-bearing wall 11 is composed of the waist wall 12 and the hanging wall 13 shown in FIGS. 8 and 9 will be described. The waist wall 12 and the hanging wall 13 are installed with the opening 15 interposed therebetween.
The upper part of the hanging wall 13 is joined to the beam member 7, and the right and left sides of the waist wall 12 and the hanging wall 13 are joined to the column members 5, 5. When seismic force acts on this non-bearing wall 11, FIG.
As shown in, the shear force of the pillar member 5 Q 1 = (on M P + M

Between the dimensions, shorter than the actual length H of the column member 5,
Become a Tanhashira, the more shear force Q 1 is increased, it becomes unsafe for the seismic force. In this case, causing the shearing force Q 1 the size of which exceeds the shear strength of the pillar member 5 acts, shear fracture the pillar member 5 (X-type (shown b) cracking) a.
To prevent this, the cross section of the column member 5 is increased,
Although there is a method of increasing the hoop of the column member 5, there is a disadvantage in designing the column member 5, and all of them increase the construction cost and the like.

な問題点がある。On the other hand, there is a method of providing a slit 14 in a conventional non-bearing wall 11. In this method, as shown in FIGS. 11 and 12, the waist wall 12 and the hanging wall 13 forming the non-bearing wall 11
This is a method in which a slit 14 having a completely opened gap is previously formed in the non-bearing wall 11 so that the column member 5 and the beam member 7 do not become short members. FIG. 13 shows the destruction situation in this case.
An example will be described. When the seismic force acts on the non-bearing wall 11, as shown in FIG. 10, the shearing force Q 2 of the column member 5 is equal to ( MP upper + MP lower) / H. Here, H is the length of the column member 5, Q 2 / Q 1 = h / H becomes, Q 2
Is much smaller than Q 1 in the above case. As described above, the method of providing the slit 14 in the non-bearing wall 11 is advantageous in terms of the shearing force of the column member 5, but has the following problems.

Covering one or both surfaces of the non-bearing wall with a continuous fiber reinforcement except for the surface of the end contacting the column member of the non-bearing wall formed by one or both of the waist wall and the hanging wall, It is constructed by generating a seismically induced slit at the end of the non-bearing wall. Here, the non-bearing wall is formed by one or both of the waist wall and the hanging wall. In the present invention, the induced slit refers to a crack induced along the column member by seismic force at the end of the waist wall or the hanging wall not covered with the continuous fiber reinforcement, and the crack is formed in the slit. By playing a role, the length of the column member can be increased, and the shear force generated in the column member due to the seismic force can be reduced.
When the seismic force acts on the non-bearing wall, as shown in FIG. 3, the shear force Q 3 of the column member is equal to ( MP upper + MP lower) / H. Here, H is the length of the column member, and Q 3 / Q 1 =
h / H becomes, Q 3 is much smaller than to Q 1 case above, during an earthquake, can be of substantially equal size and the case of providing a pre-slit.

地震時の緊急避難の安全を確保できる。(1) According to the present invention, in the event of an earthquake, the edge of the non-bearing wall is selectively destroyed to generate an induced slit, thereby alleviating the shearing force generated in the column member and the beam member. In addition, the column member and the beam member can be advantageously prevented from collapsing. (2) Since it is not necessary to provide a slit in advance on the non-bearing wall, it is possible to ensure soundproofing, sound insulation, and non-water leakage of the non-bearing wall. Further, the labor and cost for filling the slit can be omitted. (3) In the non-bearing wall provided with the sleeve wall, it is possible to prevent the sleeve wall itself from being broken due to the generation of the induced slit, so that the door provided in contact with the sleeve wall can be freely opened and closed,
Emergency evacuation during an earthquake can be secured.
