Then, as can be seen from figures 8 and 9, above-mentioned steel pipe column 2 in the enterprising line slip operation of glide direction SD, is stopped slide at the time point making steel pipe column 2 slide into the substantial middle position of basic sleeve pipe tubing 1 by operating personnel.So, vertical component 2a, 2a of steel pipe column 2 are positioned the below (state shown in Fig. 9) of horizontal member 1a, 1a respectively.In addition, in this position, also the locating stop being used for locating by abutting with steel pipe column 2 can be arranged at horizontal member 1a, 1a.Later order is identical with the order arranging circular steel pipe column 2.
Secondly, with reference to Figure 10 and Figure 11, the energy absorbing structure of steel slit dam 10 is described.In steel slit dam 10, the filler 4 be filled between steel pipe column 2 and basic sleeve pipe tubing 1 plays function as energy absorption material.And contacted by the top edge of steel pipe column 2 with basic sleeve pipe tubing 1, steel pipe column 2 plays function as energy-absorbing member.
As shown in Figure 10 (A), if horizontal load F acts on the head of steel pipe column 2, then this load is transmitted downwards through steel pipe column 2.Covered by filler 4 near the bottom of steel pipe column 2.And the basic sleeve pipe tubing 1 being filled with filler 4 is embedded in ground 30.Therefore, the load transmitted through steel pipe column 2 is absorbed by the ground reaction force of filler 4.As shown in Figure 10 (B), steel pipe column 2 now becomes region relative to its lower end side of horizontal load F by the state of filler ground spring-loaded.As shown in Figure 10 (C), along with horizontal load F becomes large, the distortion of filler becomes large, and the horizontal movement of steel pipe column 2 increases thereupon.This energy absorption utilizing filler to be out of shape proceeds to horizontal load F and reaches maximum ground reaction force and till steel pipe column 2 contacts with the top edge of basic sleeve pipe tubing 1.
As shown in Figure 11 (A), after steel pipe column 2 contacts with the top edge of basic sleeve pipe tubing 1, the wall generation depressed deformation of steel pipe column 2, carries out energy absorption by this depressed deformation.As shown in Figure 11 (B), steel pipe column 2 now becomes horizontal load and acts on upper end, and acts on the state of half-way (position contacted with the upper edge of basic sleeve pipe tubing 1) with horizontal load rightabout depression load.As shown in Figure 11 (C), along with horizontal load F becomes large, depressed deformation becomes large, and the horizontal movement of steel pipe column 2 increases thereupon.Till this utilize the energy absorption of the depressed deformation of steel pipe column 2 to proceed to crumble load and steel pipe column 2 that horizontal load F reaches steel pipe column 2 crumbles.
In addition, the horizontal load F pair of direction orthogonal with horizontal member 1a, 1a (with reference to Fig. 4 and Fig. 7) direction respect to one another acts on.In the example of Fig. 7, horizontal load F is to glide direction SD effect.As long as horizontal load F acts on this direction, then steel pipe column 2 can not by horizontal member 1a, 1a obstruction in horizontal direction top offset.So, horizontal member 1a, 1a by configuring in an opposing fashion, and can in time arranging the posture of support steel tubing string 2, on the other hand, when horizontal load F acts on steel pipe column 2, steel pipe column 2 can be made to horizontal direction displacement for avoiding bearing this load.
