Description

  The present invention relates to a reinforcing structure for a thin plate shear panel in which the vibration energy absorbing ability of the thin plate shear panel is improved by eliminating the tension field generated on the stress acting surface of the thin plate shear panel.

As a conventional reinforcing structure for a sheet steel having a square closed cross-sectional shape, there is a structure for reinforcing a sheet steel having a structure as shown in Patent Document 1 below. That is, the reinforcing structure of the thin steel plate is formed by rolling a flat thin steel plate member into a rectangular box-shaped closed cross-sectional shape, joining both ends of the thin steel plate member by caulking, and plastic foam in the inner space. It is comprised by filling.
The reinforcing structure of the thin steel plate constructed as described above is used as a structure such as a beam or a column of a house. The structure of the house is reduced in weight and the construction cost is reduced and a high axial force is provided. The purpose is to improve the seismic performance by increasing the buckling strength against bending moment.

On the other hand, the load Q in the shear direction as shown in FIG. 16B is applied to a member that does not have an internal space such as a thin plate shear panel 101 shown in FIG. Is applied, the thin plate shear panel 101 is deformed by a deformation amount δ in the shear direction, and the buckling 105 is generated by the buckling of the stress acting surface 103 on the front and back surfaces of the thin plate shear panel 101.
When the wrinkles 105 are generated, a tension field 107 is formed on the stress acting surface 103 of the thin plate shear panel 101 as shown by an arrow in FIG. Further, when the tension field 107 is formed, wrinkles 105 are generated, and the hysteresis area of the stress acting surface 103 of the thin plate shear panel 101 is reduced, and as shown in FIG. 17, it is narrow surrounded by the load-one deformation amount curve W1. The area becomes the history area S1.
In addition, if the history area is small, the vibration energy absorbing ability is lowered, and the seismic performance is lowered.

Therefore, in order to improve the seismic performance of the thin plate shear panel 101, it is conceivable to apply a thin steel plate reinforcing structure as shown in Patent Document 1 to the thin plate shear panel 101. Since there is no internal space filled with plastic foam as it is, its application is difficult.
In addition, since the stress acting surface 103 of the thin plate shear panel 101 has a relatively large area, reinforcing the entire surface causes an increase in parts cost and construction cost. Further, since the allowable space in the thickness direction of the thin plate shear panel 101 is not so wide, it is impossible to make a strong reinforcement by increasing the dimension in the thickness direction of the reinforcing member.
