Therefore, in the calculation of strength, a composite material 14 obtained by compounding an H-shaped steel member 15 having a large cross-sectional shape is used only in a portion where a large load is reliably applied, and a normal composite material 1 is used in other portions. . As a result, for example, when a large wind load is applied to the building structure, as shown in FIG.
For example, in a wooden house in which a wall material made of an inorganic material is fixed as the outer wall material 11 via the rim 12, a deformation load is applied to the outer wall material 11 from the composite material 1, and the outer wall material 11 may crack.
