Then,, as shown in Fig. 8 and Fig. 9, operating personnel in the enterprising line slip operation of glide direction SD, stops slide at the time point that makes steel pipe column 2 slide into the substantial middle position of basic sleeve pipe tubing 1 by above-mentioned steel pipe column 2.So, the below (state shown in Fig. 9) that the vertical member 2a of steel pipe column 2,2a are positioned respectively horizontal member 1a, 1a.In addition, in this position, also can be by by being arranged at horizontal member 1a, 1a with steel pipe column 2 butts for the locating stop of locating.Later order is identical with the order that circular steel pipe column 2 is set.
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 being filled between steel pipe column 2 and basic sleeve pipe tubing 1 is brought into play function as energy absorption material.And, contacting with the top edge of basic sleeve pipe tubing 1 by steel pipe column 2, steel pipe column 2 is brought into play function as energy-absorbing member.
As shown in Figure 10 (A), if horizontal load F acts on the head of steel pipe column 2, this load is transmitted downwards through steel pipe column 2.Near the bottom of steel pipe column 2, covered by filler 4.And the basic sleeve pipe tubing 1 that is filled with filler 4 is embedded in ground 30.Therefore, through steel pipe column 2 transmit and come load be absorbed by the ground reaction force of filler 4.As shown in Figure 10 (B), steel pipe column 2 now becomes the state by filler ground spring-loaded with respect to the region of its lower end side of horizontal load F.As shown in Figure 10 (C), along with horizontal load F becomes large, it is large that the distortion of filler becomes, and the horizontal movement of steel pipe column 2 increases thereupon.Till this energy absorption of utilizing filler distortion proceeds to horizontal load F and reaches maximum ground reaction force and steel pipe column 2 and contact 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 with the rightabout depression load of horizontal load in the state of half-way (position contacting with the upper edge of basic sleeve pipe tubing 1).As shown in Figure 11 (C), along with horizontal load F becomes large, it is large that depressed deformation becomes, and the horizontal movement of steel pipe column 2 increases thereupon.Till the energy absorption of this depressed deformation that utilizes steel pipe column 2 proceeds to crumble load and steel pipe column 2 that horizontal load F reaches steel pipe column 2 and crumbles.
In addition, horizontal load F pair with the orthogonal directive effect of horizontal member 1a, 1a (with reference to Fig. 4 and Fig. 7) direction respect to one another.In the example of Fig. 7, horizontal load F is to glide direction SD effect.As long as horizontal load F is to this directive effect, steel pipe column 2 can be not by horizontal member 1a, 1a obstruction and in horizontal direction top offset.So, horizontal member 1a, 1a be by configuring in relative mode, and can be in the time arranging the posture of support steel tubing string 2, on the other hand, in the time that horizontal load F acts on steel pipe column 2, can make steel pipe column 2 to horizontal direction displacement for avoiding bearing this load.
