Except for SG3600 without crimping, it shows almost the same bending properties, and it keeps a nearly proportional relationship up to about 70% of the maximum load, and it becomes a value that matches the calculation result shown by a straight line in the figure.

ない。On the other hand, the test piece (S
G3600), the rigidity is smaller than that of other test specimens due to the influence of the large lateral deformation that occurs from the initial stage of loading. At the loading point of the specimen, the compression flange came into contact with the box-shaped jig 25 to be loaded and was buckled by the middle of the test, so that the strength continued to increase, and the accuracy of the beam member 1 (specimen) increased. No maximum bending strength could be confirmed. Therefore, the load (about 55 kN) at the time when the deformation was the same as the deformation amount when the maximum load was applied to other test pieces was defined as the maximum load. Note that the test specimen SG3612 shows higher rigidity than other test specimens, but this is due to a defect of the displacement meter and is not a significant difference due to the test variables.

していることがわかる。FIG. 12 shows the relationship between the load P and the amount of lateral fall δh of the grooved beam member. Since the amount of lateral fall is measured using a wire from an external fixed point (not shown), it also includes vertical displacement, but since the distance to the fixed point is sufficiently larger than the vertical displacement, The effect of vertical displacement was assumed to be negligible. The crimped test specimens (SG3606 etc.) all show the same tendency, and although there is a difference in the direction of the lateral fall, the two grooved beam members 5a and 5b are integrally collapsed and laterally deformed. Can be confirmed. On the other hand, the specimen (S
G3600), it can be seen that the two groove-shaped beam members 5 in the state as shown in FIG. 20 are falling sideways as shown by the solid lines in FIG.

取ることができる。FIG. 13 shows the strain distribution in the center of the member span immediately before reaching the maximum load. The strain distributions of the caulked test specimens (SG3606 etc.) are all the same, and a stress gradient is generated in both the upper and lower flanges 5c, and a straight stress gradient is observed in both. From this, it is possible to quantitatively explain the phenomenon that the two grooved beam members 5a and 5b that are caulked and joined together are laterally deformed. On the other hand, from the strain distribution of the test body (SG3600) to which the web 6 is not bonded, it can be read that the upper flange 5c is laterally deformed sideways.

And the bending stiffness is consistent with the calculation result. (2) The influence of the crimping interval on the bending properties is small.

It is possible to suppress the torsion in the cross-sectional direction which has been caused, and to make it difficult to buckle. In addition, as a means of integrating pre-plated beam members or grooved beam members,
By employing caulking, it is possible to eliminate the need for prior drilling into a shaped steel for joining and a new joining member as in the related art.

After forming a beam member or a grooved beam member by bending a pre-plated steel plate, the webs in the pair of beam members or the grooved beam members are overlapped with each other, and then the webs are caulked and fixed, Since the beam members or the groove beam members are integrated without welding, the pre-plated beam members or the groove beam members can be easily manufactured from the pre-plated steel plate at low cost.
