もなる。As described above, the conventional pillar with an equipment space is provided with a partition wall having a U-shaped cross section on the side of the pillar to define an equipment space (shaft). Since an opening is provided in the capital part of the section and it is connected to the equipment space, a considerable amount of structural reinforcement is required. That is, since the opening of the capital is eccentric with respect to the column, the area of the capital is increased and the thickness of the reinforcing bar is increased in addition to increasing the area of the capital in response to stress concentration around the opening under vertical load or horizontal load. Must be increased, which is structurally unclear and also increases costs.
