Definitions
- a metal joint joined to a lower end portion of a pillar member in a building structure is arranged above the foundation concrete, and is fixed to a tip end portion of an anchor bolt protruding upward from the foundation concrete. This is also related to the column base structure where the anchor bolt yields first.
- a plate-shaped column base metal 6 having both sides of a substantially square shape is provided above the foundation concrete 3 via a mortar 8.
- This column base metal 6 is made of metal, and the lower end surface of a rectangular steel column 4 (column member) having a length in the vertical direction in the figure is joined to the upper surface 6a (surface) by welding. .
- a male screw portion formed at the lower end portion of the anchor bolt 10 is screwed to a female screw portion of the nut member 14, and a fixing plate 18 is placed on the nut member 14. It was.
- the upper end portion of the anchor bolt protruding upward from the foundation concrete is a bolt insertion hole that penetrates the thickness direction of the peripheral portion of the bottom plate portion of the column base hardware. Insert the male screw part formed on the anchor bolt into the female screw part of the nut member, and the steel column is fixed on the foundation concrete via the column base metal and mortar. It was.
- the steel column 4 in the conventional column base structure 2 is rotated clockwise around the rotation center O of the joint portion of the steel column 4 with the column base metal 6 as shown in FIG.
- the bending moment M acts to lift the left end of the column base 6 in FIG. .
- the anchor bolt 10 fixed to the left side portion of the column base metal 6 from the rotation center O in FIG. 13 starts yielding without resisting the load that generates the bending moment M and moves upward in the figure.
- energy due to a load that generates the bending moment M is absorbed.
- FIG. 14 is a hysteresis diagram (history characteristic diagram) schematically showing a correspondence relationship with a rotation angle ⁇ from a one-dot chain line (see FIG. 13) passing in a direction.
- the yield starting bending moment when the anchor bolt 10 starts yielding is the same as the yield starting bending moment when the steel column 4 starts yielding, and the force received from the anchor bolt 10. Is set smaller than the value of the yield start bending moment when the peripheral edge of the column base 6 starts yielding, and the anchor bolt 10 yields before the steel column 4 and the column base 6. It was.
- the anchor bolt 10 on the right side in FIG. 13 is the same as the anchor bolt 10 on the left side in FIG. 13 in the process from state E to state I via F, G, H in FIG. A deformation similar to the deformation in the process from the state A to the E occurs.
- the load that generates the bending moment M is not reduced at all, and the beam member or the column member constituting the upper structure may be damaged or broken by being suddenly applied, or the building structure may be collapsed. There was a risk.
- the eight beam members 56 are arranged substantially horizontally with respect to the base surface 53 and arranged in series, two by two, vertically and vertically. These beam members 56 are rigidly joined to the column members 54 at joints 58 where both ends in the length direction are abutted against the side portions of the column members 54.
- FIG. 10 and 11 are diagrams for comparing the column base absorbed energy index (W1 / W0) of the conventional column base structure 2 and the column base structure 40 according to the present embodiment.
- FIG. 10 shows a comparison of the column base absorbed energy index in the case of the two-layer model 50
- FIG. 11 shows a comparison of the column base absorbed energy index in the case of the four-layer model 52.
- the column base absorbed energy index is the exposed column base absorbed energy W1 that can be absorbed by the conventional column base structure 2 or the column base structure 40 according to the present embodiment, and the column member 54 in the embedded column base.
- the column base absorption energy that can be absorbed by the column base structure is increased as the value of the column base absorption energy index increases. The amount will be large.
- the exposed-type column base absorbed energy W1 is calculated from the hysteresis diagram of the conventional column base structure 2 or the column base structure 40 according to the present embodiment as shown in FIGS. Yes.
- the column base structure 40 does not cause the slip phenomenon as in the conventional column base structure 2, so that the bending moment M is applied to the lower end portion of the steel column 4, the column base bracket 42 and the anchor bolt 10. Since a part of the generated load is applied, the load that generates the bending moment M is not applied to the beam member, the column member, etc. constituting the upper structure above the column base structure 40, and the column base structure The superstructure above 40 need only bear part of the load.
- the column base hardware 42 is a flat plate having both square front and back surfaces. It may be a rectangle.
- the column base hardware may be configured by a bottom plate portion and a support base portion in which a central portion of the upper surface of the bottom plate portion protrudes upward from the peripheral edge portion thereof, like the column base hardware according to Patent Document 2. Also, other shapes may be used.
- the male screw portion formed at the lower end portion of the anchor bolt 10 is screwed to the female screw portion of one nut member 14.
- Two or more nut members 14 may be attached, or a fixing plate 18 may be provided between the two nut members 14.
